Dune Cheats

Recommended Posts

Start with lots of spice

The following archive includes Dune saved games with over 393 tons of spice in stock, which should be more than enough to pay the emperor and buy weapons and other goodies from smugglers without the need to have troops dedicated to spice extraction. The save games were made early in game (at a point where you normally have only a few kilograms of spice).

Get it there: Dune savegames.7z (more info)

Hexadecimal cheats

With an hexadecimal editor, you can quite easily edit some characteristics of your troops:

Motivation: convert the current motivation to hexadecimal. For instance, a 100% motivation would be saved as 64 in the save file.

Number of fremens in a troop: divide the troop size by 10, then convert to hexadecimal. For instance, a troop will 2540 men would be saved as FE in the save file.

Equipment: see the sub-section below

So, with your hexadecimal editor, open the saved game you want to edit (make sure you save a backup first!): DUNE37S1.SAV or DUNE37S2.SAV (37 is the number corresponding to the game version, it may be different for your version). Search for the values you want to edit, knowing that troops information are located approximately in the last third of the save file, and that the structure for a troop is like:

...X[motivation]XXX[equipment][population]X...(Each X represents a byte, motivation is 4 offsets before equipment, which is right before population).

[edit] Equipment cheat

The [equipment] value is a bitflag (here listed as decimal values [hexadecimal value]) where:

1 [1] = not assigned

2 [2] = bulb

4 [4] = atomic weapon

8 [8] = weirding modules

16 [10] = laser guns

32 [20] = krys knives

64 [40] = ornithopter

128 [80] = spice harvester

So, to give all equipment to a troop, set this value to 254 [fe]. This cheat generates a minor bug: the equipment is registered as troop equipment, but not as sietch equipment. This means that if you unequip the equipment you added, it will vanish. The solution to this bug is to move your troop to another sietch, which will register the equipment for the sietch.

I think you can even edit the harkonnen troops to make the game more difficult.

I have edited the file. Leto is now willing to follow you lol

Does anyone have a detailed guide on editing save games? I'd like to edit a Day 1 save game in order to make a more difficult scenario. More and stronger Harkonnens etc.

Hi all!

Yes Neil, here is one. One and a half years later.

Here is my tuto to hex editing savegame file. Thanks to apologize my spells. English is not my natural tongue.angel.gif

HEXA CHEATS

I've based my work on this wiki page found on www.wiki4game.com.

Lots of useful infos & tips were found there:

www.wiki4games.com/Dune#Hexadecimal_cheats

======================================================================

Preliminary notes:

Repeat-byte [0xF7xxxx]. It's used to convert 3 minimum consequential and identical bytes.

The game never use triple identical bytes (or more) as a result. Instead the soft use [0xF7] repeat byte. I've seen [0xF702XX] very rarely, a the beginning of the savegame file. Don't know if it's a repeat-byte...

Ex: [0xF704C0] in the file means [0xC0C0C0C0] => (F7Repeat)(4Time)(ByteC4)

[0xF764FF] ------------------>[0xFF.......98times.....FF]

It's used in the file's frame many times. You 'll have to transcribe all the redundancies of 3+ bytes at the end of your changes before applying them and saving your work for better compatibility, but it's not required most of the time (for little editing). The method is really simple. For few bytes, like [x00000000000000000000], (00 X 10) bytes, you've to write "F70A00" instead of such expression. If you experience too more bytes that can't be counted manually, I advise you to copy/paste the sentence in Notepad++ or an HexEditor to do it for you (look in the status bar).

Take care not to interpret a Repeat-F7 byte like a false-negative: [0x....8F720095...] => ...[0x8F]&[0x72]&[0x00]&[0x95]... There's no [0xF7] here.

There's little exception[0xF701F7] means [0xF7] to avoid the deflating byte to be proceeded. tongue.gif And the [0xF70200] that haven't to be converted.

======================================================================

SIETCHES CHEATS

Here is the Sietches structures in the savegame file (Cf.Attachments :DUNECD_Savefiles_Sietches.zip) that I posted.

Sietches structure starts at offset d6038 and ends at offset d7701. The last bytes of the structure and the last sietch ends at offset d7727.

This structures is [0xF7]deflating bytes free (Cf. upper). I've converted them into what it's represent. The only exception is the double "=" that I use in order to replace the [0xF701F7] to keep consistent layout.

Example: in order to change the name of 'Carthag (Atreides)' to 'Celimyn-Pyort', find the sietch beginning with '02 01' and change it to '0c 0b'.

B: [GPS Location]

Don't really know what this mean but it seem to be a localization system. We find the same 4 bytes in the troops bloc which stay in this sietch.

C:[Appearance]

Appearance of sietches interior (HAVE TO BE CONFIRMED).

D: [Housed Troop ID]

Troop which are living/posted in the sietch/fort at the beginning. Refer to the Troop section and *.ods file for more informations.Sietch inventory & troops features v0.1.zip

Some sietch haven't got troop, but, in the Harkonnens forts, there are more than one troop posted there. It's noticed in the structures of the troop section of the savegame file. We can know by this way, which troop come after in the place.

E: [status]

This value is a bitflag (here listed as decimal values [hexadecimal value]) where:

0 [0x00] = visible sietch/village/palace

1 [0x01] = vegetation present (no more spice mining possible)

2 [0x02] = in battle

4 [0x04] = ?

8 [0x08] = ?

16 [0x10] = see the inventory of the sietch

32 [0x20] = wind-trap constructed

64 [0x40] = area of sietch has been prospected

128 [0x80] = sietch has not been discovered

160 [0xA0] = sietch with wind-trap wich has not been discovered

224 [0xE0] = Tuono-Tabr before stillsuit mission --> Hidden + Wind-Trap + Prospected

A sietch wich has been prospected, visited (inventory visible), and wind-trap constructed will have the [statut] byte : [0x10]+[0x20]+[0x40]=[0x70]

The bitflag [0x80/0x40/0x10] are pretty useful ;)

Maybe can we refill spice area by changing the [0x01] and the I column?

G: [spice field ID]

Not studied...

Are present, bytes between 0[0x00] & 76[0x4C]; except [0x0A],[0x0E],[0x2E],[0x30],[0x42]&[0x4B]. Same trip as multi primary troop?

I: [spice density]

Spice density in the relevant area. A picture will be more expressive.

59ef322d-8773-4b4a-b8fe-20ef8a7b359b.jpg

Values between 0[0x00] et 250[0xFA] in gamefile. 0[0x00] for villages & palaces: zipped by the repeat-byte [0xF7], the unknown byte and inventory's ones.

K: Inventory

Pretty simple here. Just convert in hexadecimal the desired amounts of stuff you want to get in the concerned sietch and replace associated bytes in the siecth bloc.

Ex: Tuono-Tuek

Adress d6817:

[0x03052F4DFCFF3C5D0409800400000000262AB4000F00000000190000]

I add 15 Harvesters & 25 Atomics weapons.

L: [Water]

Water supply amount (w/wo wind-trap).

It's time now for a little practice:

I write this completly from nothing. No idea what it could turn.

Admitting we want to make an invisible sietch to be visible to the map.

Ergsun-Timin for exemple. Based on its name, we found in the table that its [Firstname]+[Lastname] is coded 0804. So, open your savegame in your hex editor and find all occurrences of the short byte[0x0804].

In the earlier savegame file, there's only one offset. We are lucky. So find now the second sietch in the list ([0x0805]) -in other words, the stop position- and copy all the bytes of Ergsun-Timin sietch in a text editor like this:

[0x08047FC4E8FF8E3F040F8028F7040038356EF7030001F70500]

Look for the deflating byte. To avoid the false [0xF7], your could spaced all binomial. Counting seriously will make the deal. Transform the deflating byte to real form. If it was well done, you 'll have 28 bytes to study and to modify. If not, try to see if there's no [0xF701F7] (See Preliminary notes).

In my savefile I had this:

[0x08047FC4E8FF8E3F040F80280000000038356E000000010000000000]

Now find the [status] byte at position number 11. There's a [0x80]. The table tells that 'sietch has not been discovered'. Let's modify this cool.gif . Enter [0x10] (visited) or [0x40] (prospectead). No need to add deflating byte. Copy/paste your modif in your savegame at the good place and save your file (need a "special paste" in HexWorkshop. In overwrite mode if you copy and insert mode if you cut your bytes). Go to the game and load it. Ergsun-Timin is now reachable by orni.

If you want to refill or upgrade the spice density of the area to harvest more spice. Edit the byte number 19. And write [0xFF]. Want water? Edit the last byte etc.

Inventory is a not really complicated. Convert the desired amount of stuff you want in hexa and fill the byte position shown in reference table. You can add weapon to harkonnen Fort, but you'll had to edit the troop structure to be usable by them ( -- HAVE TO BE CONFIRMED).

If you find more result in the search of the sietch's heading, you can use more byte of my table. Generally, 8 bytes will take you to success; Or you can find another sietch and count bytes if you are experienced.

SPICE CHEAT - Temporary little credit or Cresus wealth

In the savefile submitted, spice's amount is located on the offset d5595. 8 bytes before Harkonnens amount. For your savegame ,click on DUNE MAP ingame & look the Arrakis globe and click on SEE RESULT. Watch the Harkonnens spice production. Divide by 10 the value and convert this decimal value in hexa short byte (Intel order). And find it in your savegame file.In my file, it's located offset d5995.

The Atreides amount is located 8 bytes before this offset. Considering the deflating byte [0xF7], you can find it's good location. Spice structure in my savegame file is as shown: [0xF780008601]. The solution is to split the deflating bytes into 2 deflating blocs surrounding the modified converted Atreides spice amount .

Exemple: I want add 10000Kg to my empty starting stock. d1000 = hE803. After translation this gives me [0xF77800E803F706008601]

F77800 = [0x78] that to say 120 bytes zeros filled

E803 = Atreides spice amount (10x1000 Kg, [h03E8])

F70600 = [0x06] that to say 6 bytes zeros filled

8601 = Harkonnens spice amount (10x390 Kg, [h0186])

120 bytes zeros filled + 2 bytes Atreides spice amount + 6 bytes zeros filled = 128 bytes that to say h80 of the original deflating bloc [0xF78000].

I don't know if it changes the game's progress to make Harkonnen richer...

CONTACT DISTANCE CHEAT

From a certain point in the game you can contact your troops from a distance. The initial range of contact distance is set to 0x01, which means that you can only contact the troops in the sietch you are at that moment. You can change this by altering a byte near the end of the savegame, so you don't need to travel as much to give orders.

The byte responsible is a bit tricky to find, but in the initial savegame it's at byte 9601(0x2581)9600(0x2580) and it's before 2 bytes which always seem to be '00 FF'. So if you want to change this before waiting in the desert for the message of the first spice shipment you'll be looking for [0x0100FF]. A contact distance of [0xD0] already covers the entire planet, but a value of [0xFF] may be set.

For me, I simply find [0x0100FF] at offset d9600. [0x0100FF] was present only one time in my starting savegame file.

TROOP CHEATS

Troop structure begin at the end of sietch structure. Each troop begin by Troop ID are 27 bytes long (decompacted).

Here is the listing of the early troop structure deflating byte [0xF7] free.

[0x80]->[0x9F] = Not yet hired

[0xA0]->[0xFF] = Complain about slaving by harkonnen

F: [GPS location]

Refer to an unknown localization system of the sietch occupied currently. (See. SIETCH - B: [GPS Location])

I: [speech]

[0x01] = ?

[0x10] = Gives the message that a fortress has been transformed into a sietch

[0x20] = Spice skill showing in troop characteristics

K: [Motivation]

128 [0x80] = spice harvester

So, to give all equipment to a troop, set this value to 254 [0xFE]: 2+4+8+16+32+64+128 = 254.

This cheat generates a minor bug: the equipment is registered as troop equipment, but not as sietch equipment. This means that if you unequip the equipment you added, it will vanish. The solution to this bug is to move your troop to another sietch, which will register the equipment for the sietch.

P: [Population]

Divide the troop size by 10, then convert to hexadecimal. For 2550 fremen in the troop, write [0xFF] in the savegame file at this offset.

This post was really painfull rolleyes.gif

If you have question, I'll be glad to answer you.

I don't break all the secret of these blocs, I planned to attach a mega-cheated savegame file, but, it'll break the interest of the game.

So, if you want a Cresus, all sietch visible, max pop & max motivation, full of stuff troop & sietch and big dstance communication, just tell me, I 'll do it for you.

I don't look for Charisma, but it'll not be very difficult I tink.

I'm open to your suggestion or idea to enlarge this article.

Hi,

I would really appreciate a save game with max population, max motivation, each sietch full inventory, and large distance communication with also large amount of spice.

Thanks,

Ben

Hi Guys.

This was one of my favourite games ever back in the days.

I enjoyed this game so much that I just had to create my own Savegame editor.

Unfortunately I only saw this thread a few weeks ago otherwise I would have done this a long time ago.

In the Editor you can Edit the Amount of Spice you have, Charisma, Contact distance, Troops with equipment and the Sietches with their equipment.

Excuse my english as it is not my mother tongue.

Anyone interested in the Editor? I will be happy to share.

Cheers!

Nice! Can you upload it somewhere permanently and post a link here? Otherwise (if it ain't a large file) you can just attach it to your post (note that forum software rejects RAR and 7zip archives for some reason).

Sorry for the late reply. I did not get an email notification.

I have attached the doc file with the exe file embedded and I hope it works.

You might need to install dotNetFramework4.

For the ones that does not trust this and have visual studio, I will share the source code.

I'm not sure if it's working correctly... I get loads of "troop 00" occurrences, and the sietches list shows odd name combinations too, with values like 255 laser guns and 128 krys knifes. I wonder, are there different versions (with different savegames) of Dune 1?

Anyway, I'm a programmer, and I'd love to take a look at the code. What programming language is it?

There are different versions of the savegame.

I tested this with the CD-version and the lists looked correctly.

I made this page to collect all the info I could find, its on google pages - in the hope that spot will never vanish..

http://sites.google.com/site/duneeditor/savegame-editing

Will have to add this excellent editor!

It would be nice if would share the source code, I think there is still more to discover in the savegame, for example the ecology. As it seems the savegame 0 - is the data for starting the game, maybe it would be possible to create a different scenario for Dune. raising the difficulty, without changing the actual game code.

If you want to keep the savegame of older positions in Dune it's sufficient that you copy the .sav files in the game main directory to other locations, then restore them when you want to replay without restarting Dune.

The .sav files are:

dune23s0.sav (-> dune37s0.sav in the CD-version): it represents the option "Restart game";

dune23s1.sav (-> dune37s1.sav in the CD-version): it represents the first save slot;

dune23s2.sav (-> dune37s2.sav in the CD-version): it represents the second save slot;

dune23s3.sav (-> dune37s3.sav in the CD-version): it represents the option "Last place you have visited";

dune23s4.sav (-> dune37s4.sav in the CD-version): it represents the option "Last new sietch explored.

Remember to make a backup copy of these files, before you do anything on them! ;)

Hello, I am new here and being playing the classic Dune through DosBox. Used to have it years and years ago on my old 386SX!!!

Anyway, been playing for a while now and had to restart a few times due to not having enough spice and things and then I found the file here to start with loads of spice, only cheat I have used and been playing for ages finding and beating the Harks, planting seed etc, must be about 3 quarters through and that greedy Emp has nearly had all the 300000+kg of spice.

So can someone tell me where to find the spice value entry in the saved file and what value to change it to to have maximum spice again, I don't want to start the game again.

Problem is I do not understand any of this hex editor stuff so I really need someone to take a look at my saved file, maybe do a screen dump which they can email back to me and show me exactly where the spice value is, also what hex editor programme should I search for and download?

Tried the Dune editor programme but it says the file is saved with max spice but when I load the game nothing has changed....

Also my files are the Dune21S1 ones.

Please reply here or email me at sferg.410@ntlworld.com and i will happily send you a copy of my saved game file and you can show me the spice value location.

Thanks a lot

TIME ON DUNE

The day is divided in to 16 units. That makes them 90 minutes long. Each

unit takes 60 seconds of real time. That makes a day 16 minutes long. The

minimum time is Day 1 12am. The default time is Day 1 4:30am. The start time is

Day 1 9am. The clock goes to Day 365 10:30pm and then resets. The results go to

Day 999 10:30pm. The maximum time is Day 4096 10:30pm. Wait for morning is

4:30am. Wait for evening is 10:30pm. Travel makes time go by at a faster rate.

The two bytes that contain the Date & Time always follow a set of constant bytes. I checked a save game from way after the last fortress was captured and I was messing around mining all the spice and growing vegetation. Those F7 compression bytes never changed from zero.

v2.1 C3 89 B2 FF FF F7 24 00 xx xx DT DT

v2.3 C4 89 B2 FF FF F7 30 00 xx xx DT DT

v3.7 C9 85 D6 FF FF F7 68 00 xx xx DT DT This same string is also in DUNE38Sx.SAV

The xx xx seems to be a sub hour counter that goes from 0 - FFFF. Set it to zero when you change the DT. I have seen the least significant byte of this value be 00 which of course pops that F7 compression value up by one and moves the DT value over by one.

Here are some DT values and what time they show on the saved game name (Log 1 or Log 2).

FF FD = Day 1 12:00am

FF FE = Day 1 01:30am

FF FF = Day 1 03:00am

00 00 = Day 1 04:30am

00 0D = Day 2 12:00am

16 CC = Day 365 10:30pm

3E 6C = Day 999 10:30pm

FF FC = Day 4096 10:30pm

The two DT bytes are stored reversed (least significant to most significant byte order). If you are calculating a date to set, you need to subtract 19 dec from what you think it sould be. Day 2 12:00am should be 2x16=32. Subtract 19 before writing the value and it will be correct. Day 10 12:00pm would be 10x16+8=168-19=149 or 95hex. You would write this in the file as 95 00 or 00 00 95 00 to set the subhour counter to zero.

Not understanding this lol. I tried to divide my spice by 10 then used a converter, searched with a hex editor of the save file can't find it. Lol. Any tips on first time hexedit users?

It would be helpful to see a YouTube walkthrough? My hangup is in my hex editor I'm seeing small 2 digit columns.. Not sure exactly what I'm doing wrong. I mean I edited eurotruck simulator 2 using a hex editor but it was a breeze following a walkthrough. Please? Thanks

You are close Taterz. You need to search in LSB-MSB order. The four digit hex number you have must be split in to two pairs of hex numbers and then reversed. As in Duncan reports 73110kg of spice. 7311 to hex is 1C8F. Search for 8F1C. In the unlikely event of more than one 8F1C strings, it will be the one near the end of the save game file. If the sun and moon move between Duncan's report and you saving the game, than spice stocks will be higher than the value you are searching for. The time updates every one minute of real time. And you could ask for the report near the end of a minute. If it doesn't seem to be working just load the saved game, ask Duncan again and the immediately resave the game.

For anyone super curious, the first byte of column F in John2022's sietch structure is used to determine when a sietch can be discovered. For example, Tuono-Tabr is set to 02, so when the game stage variable is 02 (which it is when Leto orders you to find the stillsuit maker), the sietch becomes discoverable.

The game stage only goes up to C8 (I think), so those locations set to FF are revealed through other events.

If the game stage variable never goes to 0xFF, that explains why nobody can find Celimyn-Tuek by traveling into that area of the desert with an orni or a worm... it's revealed by meeting none of Harah (the first byte should then be 0x14), Chani (should be 48) or even Liet Kynes (should be 58). I guess I'll test that by editing the first byte of the F section early in the game to say 14, next time I play the game :)

[EDIT: yup, unsurprisingly, if the first byte of the F section of Celimyn-Tuek is set to 0x14, then that sietch can be found by flying over the area, right after meeting Harah.]

Spice refilling is a cool hack, but having to resort to it indicates that something's wrong with the way the player is playing the game. The game can be won without sending more than 10 tons of spice to the Emperor, and without cheating either; the area where the game starts, bounded by the rocky areas at the north and east, down to Habbanya-Tabr in the south, and comprising Habbanya-Clam + Oxtyn-Harg in the west (well, everything you can find with Harah before going to Stilgar's area), contains far more than 10 tons of spice. Even by playing in a somewhat more relaxed way - it's been over two decades since I started consistently beating all of the Harkonnen fortresses by day 30.

I never saw the Sardaukar, I guess I should try it once... assuming they're supported by my old version which creates DUNE21S*.SAV files. IIRC, the only time I failed to send enough spice to the Emperor in a timely manner, Paul Atreides died even when he wasn't in the Atreides palace. That was beyond day 80...

Hello to everybody

I have a trouble with both the editors.

Referring to the website https://sites.google.com/site/duneeditor/savegame-editing-v2 , I have everytime crashes after modifying the savegame file

When I use the savegame editor (CD), it modifies the geometry of the palace (I can enter in not-discovered-yet rooms, and after that, I'm not able to enter in the weapon room. If I try to speak with hara, the game crushes)

When I use the savegame AIR editor, the game crushes if I try to join the mail hall of the palace

 

Someone else had this kind of problem, and how did you solve? 

I was thinking that maybe the problem is my version (actually, according to the savegame file, il 3.7).

 

Bye

Another cheat in the time area, which I never saw described anywhere...

 

At least in the version which creates DUNE21S*.SAV files, one can take advantage of the automatic save when entering into a place, and Maps -> Globe -> Load game -> Last entering into a place, to cram a higher number of character dialogs - sequences and/or troop actions per 1h30 time period. The sub-hour counter doesn't seem to be adequately saved or restored.

 

I've been using this cheat occasionally for years; using it intensively has a surprisingly deep impact (read: several days !) on the game's internal time, obviously at the expense of the playing time in the real world. That's how, last week-end, I had:

  • Paul Atreides meet Chani, drink the Water of Life in Tuono-Tabr, get back to the Carthag palace and talk with Jessica to get the Fremen contact range boosted, before the end of day 9;
  • the Fremen destroy all Harkonnen fortresses (and Paul Atreides enter all of them + recover Chani + rally all 47 troops, reaching less than 78000 Fremen total - some game runs provide more than 81000 Fremen in these 47 troops) at the end of day 16;
  • the ability to trigger the final attack from Arrakeen-Tabr on day 17, 4h30, and therefore the ability to enter the Arrakeen (Harkonnen) palace at the same timestamp by going to the palace and launching a massive attack.

without editing the save game beyond changing the first byte of the F section of Celimyn-Tuek to 14 right after meeting Harah, as mentioned above. This even slows down the game by one period (moving from Tuono-Timin to Celimyn-Tuek then from Celimyn-Tuek to Habbanya-Tuek, instead of moving directly from Tuono-Timin to Habbanya-Tuek), in fact...

Several pieces of information about how I made that game run, and their consequences:

  • zero Fremen killed by the Harkonnen, thanks to undoing / repeating several close battles multiple times (you usually end up being lucky at some point), and maybe 20 or 40 killed by sandworms (but no harvester swallowed, I undid that);
  • no saboteurs, I undid that as well;
  • only two spice shipments to the emperor at the end of day 3 (more than the Emperor asked for) and on day 9 (twice what the Emperor asked for);
  • dozens of tons of spice mined as usual, since most troops from the Southern part of the planet kept mining spice;
  • obviously, the prospectors troop didn't get around to prospecting the northern part of the planet, despite being equipped with an orni around day 9 (10 ?).
  • equipping your army troops with ornis very early, the first one even before attacking the Bledan fortresses, helps a lot with espionage and attack;
  • attacking the Harkonnen very early (days 5-7) in the Bledan region prevents sietch attacks from the Harkonnen in e.g. Carthag-Tabr;
  • the fortresses in the Tsympo area are relatively easy to attack after picking up weirding modules from the Tsympo sietch;
  • after winning battles in the Tsympo fortresses, then Arrakeen-Siet, you have enough equipment to attack Arrakeen-Tuek. I only figured that fairly recently. Even 12000+ inexperienced Fremen with inferior equipment can run over less than 2000 atomics-equipped Harkonnen, especially if you reach the fortress using a worm during the attack to boost your troops' motivation. Then, it's basically game over for the Harkonnen, as the atomics picked up there open up the door to e.g. the Haga region (possibly precedeed by Arrakeen-Clam, I don't remember what I did exactly) and its relatively easy weirding modules and atomics, which will be required for the rest of the Arrakeen region. Destroying Arrakeen-Tuek early has another upside: long before you get to attacking Arrakeen-Tabr and Arrakeen-Timin, Arrakeen-Tuek is transformed into a sietch, into which, unlike a Harkonnen fortress, you can tell Stilgar and Chani to stay while you're getting back to the Atreides palace to pick up Thufir Hawat and Jessica and bring them to one of the three locations closest to the Harkonnen palace;
  • lots of free travel was used between sietches / fortresses, especially in the Arrakeen region (Tuek -> Tabr -> Clam -> Tsymyn -> Timin, Clam -> Harg) - extremely useful when visiting fortresses and moving characters from the Atreides (Carthag) palace to Arrakeen-Tuek, for instance;

It's pretty clear to me how this blueprint for a low internal game time can be beat with Dune version "21", as I didn't take advantage of multiple strategies, such as but probably not limited to:

  • starting ecology experiments to boost troop motivation;
  • moving to e.g. Carthag-Timin (instead of Tuono-Tabr) the army troop which I had Gurney Halleck train for several seconds in order to save two 1h30 periods flying in an orni between the sietch and the Atreides (Carthag) palace;
  • using Gurney Halleck to train army troops. After letting him once in a sietch to trigger Baron Harkonnen's phony message which causes Leto to depart, etc., there's so much to do moving all over the planet with Stilgar and Harah in the beginning, then Stilgar and Chani, to enter / discover sietches / villages / fortresses that there was little opportunity to pick up Gurney Halleck back from the Atreides (Carthag) palace;
  • using the same set of army troops in a smarter way: 4 of them ended up being ill together, and I didn't even bother undoing it because they had both low training and low equipment;
  • converting spice troops from the southern half of the planet to army troops, though I'm not sure that would have helped much because of a lack of equipment, unless I resorted to...
  • ... grabbing (more) weapons from the smugglers: I think I used the one in Tuono-Pyons for spice harvesters and ornis, but not for weapons, and if I bought weapons from the one in Tsympo-Pyons, it was too early in the game for him to offer weirding modules.

And besides this set of options, maybe there's some even smarter game strategy I haven't yet found in 20+ years of using the game on and off :) 

Also, without impacting the total game time, the spice mining troops could have mined quite a bit more spice if I had moved them to richer areas in the south.

 

Without using this auto save / load game cheat intensively, it's probably hard to avoid making three spice shipments to the Emperor, e.g. on days 3, 9 and 17 (well, that one can be delayed to 18 or 19, the Emperor will just get angry). However, having to make four spice shipments is a sign of a suboptimal attack strategy, as all Harkonnen fortresses can be easily destroyed by the end of day 23, even without using this auto save / load game cheat (I hadn't found it 20 years ago), and the fourth shipment can be made to occur on day 24 or 25.

 Hi Guys,
There has to be a section in the save game files which stores who is in Paul's inventory.  I've been messing with the save games, and somehow i've "lost" Gurney and Chani.  The troops tell me he's excellent at training them - but he's not in the Sietch.  He's nowhere.  Chani was lost at about the time she should have tending to the ill.  I noticed her bug, she appeared visible on every screen until Duncan took her place, then she vanished.  
Has anyone found in the save files where the non-troop characters (Mum, Dad, Gurney, Chani, Harrah, Duncan, Liet, Hawat) are located?

So, the Fremen units you get from liberating Harkonnen fortresses don't appear in any of those lists. Are they randomized? I think you are guaranteed to get a troop whenever you win a battle for a fort, but I think if you take over an abandoned fort, there won't be a Fremen unit there.

Yes, the Fremen troops you can recruit after liberating Harkonnen fortresses are randomized. The appearance of their respective leaders is always the same for the troop "belonging" to a given fortress, though on Dune "21" at least, there's occasionally a glitch where the Fremen leader notifying the player of a battle being won is neither any of the Fremen leaders whose troops won the battle, nor the Fremen leader of the troop you can recruit after entering the location and possibly having a Harkonnen captain captured. This glitch occurs especially for Arrakeen-Tsymyn.

However, the number of Fremen, and to some extent the sietch equipment left after the battle (especially in the Bledan area), are randomized, yielding a total number of Fremen on the planet between ~74K and ~81K, without losing any Fremen in a battle. The head count randomization is performed around an average value. Usually, after destroying the four Bledan fortresses and recruiting formerly slaved Fremen troops, you have a good estimation of how many Fremen you can count on for attacking fortresses, and therefore whether the game will be easier (~8K Fremen in the Bledan area, if you're lucky) or harder (~5K-6K Fremen in that area).

character data is right after troop data and is laid out something like this:

         a  b  c    d    e    f  g  h
leto: 200a 80 01 dc9d 0000 0000 00 02

A :  the scene this character appears in (see field C of sietch data) + the room within the scene (in this case, the throne room of the palace)

:  i *think* this is used for distance from a location if you leave someone in the desert?

C :  character is hidden when this is set to ff

D :  this is a function pointer used to start dialogue and i have no idea why it's present in save games

E&F :  unsure. these are set to zero at game start (thus compressed in save games)

G :  sprite index

H :  unsure

characters appear in this order: leto, jessica, thufir, duncan, gurney, stilgar, kynes, chani, harah, the baron, feyd, the emperor, soldiers, smugglers, fremen, fremen

I have edited the file. Leto is now willing to follow you

Do we have someone here who's aware of what bytes & at which offsets are responsible for a character's willingness to follow the player?

Is there a chance you could provide the exact version 3.7 offset which is responsible for the definition of Game Stage variable, along with initial associated data contents by the time when the game starts? Thank you. :)
