Hi all. I'm starting a little project, and looking into changing some sprites/title screens on a Genesis/Mega Drive game for part of the hack. So far my text hunting and changes seem to be working fine, but when it comes to graphics changes, having a few issues though...
Firstly, how can you get palette data from a genesis ROM? I've loaded up the game in tile layer pro, and can find some of the tiles I want to edit, but all the colours are wrong. Where do I get the palette information from?
Secondly, in the part of the title screen I want to change, some tiles are reused - and the graphic I want to replace it with won't have tiles duplicated... Where would I start looking for the layout information in the ROM?
Is there any good source for information on this, or any tips you guys have?
