Most people wouldn't notice this, but I spend entirely too much time drooling over the MM8BDM palette.

At the top is Galaxy Man's base sprite, and also the translation GALAXYMAN (887), as seen in COLORS.acs. It doesn't do practically anything, but it's there.
CreateTranslation (GALAXYMAN, 192:192=192:192, 198:198=198:198, 207:207=207:207, 240:240=207:207);
The first row is straight from Mega Man 9. Those are his original colors, from the original game.
The second row is translations GALAXYMAN1 (890) through GALAXYMAN7 (896), also seen in COLORS.acs.
CreateTranslation (GALAXYMAN1, 192:192=4:4, 198:198=205:205, 207:207=206:206, 240:240=206:206);
CreateTranslation (GALAXYMAN2, 192:192=4:4, 198:198=58:58, 207:207=60:60, 240:240=60:60);
CreateTranslation (GALAXYMAN3, 192:192=4:4, 198:198=39:39, 207:207=40:40, 240:240=40:40);
CreateTranslation (GALAXYMAN4, 192:192=4:4, 198:198=225:225, 207:207=227:227, 240:240=227:227);
CreateTranslation (GALAXYMAN5, 192:192=4:4, 198:198=229:229, 207:207=230:230, 240:240=230:230);
CreateTranslation (GALAXYMAN6, 192:192=4:4, 198:198=104:104, 207:207=111:111, 240:240=111:111);
CreateTranslation (GALAXYMAN7, 192:192=4:4, 198:198=103:103, 207:207=116:116, 240:240=116:116);
The third row is a set of translations created in MAP01's scripts, which the Galaxy Man prop uses.
CreateTranslation(600, 198:198=[247,181,0]:[247,181,0], 192:192=4:4);
CreateTranslation(601, 198:198=[181,247,16]:[181,247,16], 192:192=4:4);
CreateTranslation(602, 198:198=[82,247,148]:[82,247,148], 192:192=4:4);
CreateTranslation(603, 198:198=[148,115,247]:[148,115,247], 192:192=4:4);
CreateTranslation(604, 198:198=[247,82,148]:[247,82,148], 192:192=4:4);
CreateTranslation(605, 198:198=[247,115,82]:[247,115,82], 192:192=4:4);
So what's the problem, then? Inconsistency. The translations in COLORS.acs translate too many colors, which isn't faithful to the original game. On the other hand, the RGB notation used in MAP01 is fine and all, but it's missing an entire translation.
The fourth row is my solution: dropping the extra color from COLORS.acs. It closely resembles those seen in Mega Man 9, while drawing straight from the MM8BDM palette.
CreateTranslation (GALAXYMAN, 192:192=192:192, 198:198=198:198);
CreateTranslation (GALAXYMAN1, 192:192=4:4, 198:198=205:205);
CreateTranslation (GALAXYMAN2, 192:192=4:4, 198:198=58:58);
CreateTranslation (GALAXYMAN3, 192:192=4:4, 198:198=39:39);
CreateTranslation (GALAXYMAN4, 192:192=4:4, 198:198=225:225);
CreateTranslation (GALAXYMAN5, 192:192=4:4, 198:198=229:229);
CreateTranslation (GALAXYMAN6, 192:192=4:4, 198:198=104:104);
CreateTranslation (GALAXYMAN7, 192:192=4:4, 198:198=103:103);
Then, apply it to MAP01. Quick and painless.
