Great job here with the remake. But I have a question: what is that "weird" sound when it plays "construction complete"? Should in table/sound.c instead of const Feedback g_feedback[VOICEID_MAX] = {{{0x002B, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF}, 0x33, 0x003C}, /* 0 */be const Feedback g_feedback[VOICEID_MAX] = {{{0x002B, 0xFFFF, 0xFFFF, 0xFFFF, 0xFFFF}, 0x33, 0xFFFF}, /* 0 */? There seems to be more "dual sounds", maybe the sound enhancement?
