Hey, fairly new, sorry if this is in the wrong place. I'm interested in editing some sprites for Marvel VS Capcom 1, particularly the arcade version. I'm seeking specifically to edit the Morrilith sprites to appear as Lillith. I've done some Neo Geo KoF sprite edits, so I understand that the game uses tiles and the sprites will need to be chopped up into 16x16 squares. My main question is accessing those sprites from the MAME/Arcade version of the game, extracting them, editing them, and then successfully injecting them. What tools do I need? Which files are the "important" ones in the rom?
I am also curious to know if anyone knows if the "alt" characters (Shadow Lady, Morrilith, Gold War Machine etc) are actually their own sprites, or if the game just calls on the existing sprites and modifies the palette. If that's the case, then this idea is kind of SOL.
Another thing I'm interested in is modifying the game to allow the "Bonus Characters" to be selectable without the inputs needed on the arcade mode. If possible, adding their actual portraits would be a wonderful bonus. Their slots already exist on the select screen, it's just a matter of doing specific inputs to select them. I'd like to remove that need for inputs.
