Anywho, since I made this list, I'll release it. All of the art is uncompressed. While the list is incomplete, it's more than enough information to create a decent art hack. Also, I think I may have found an unused goodie or two, such as gameplay styled chao sprites. The stuff I think is unused has been highlited in red.
* Table Removed, it was fucking with the post *
I'll stress, this list is nowhere near complete. These locations are from a US Sonic Advance rom, so if you're using a japanese/euro rom, the locations might not match. All locations found by ThunderSpeed... though just about anyone could've found 'em. =P
Also, due to not knowing where the mappings/collision for the levels are, level art edits have to be kept to the basic shape of the current art.
As you may have guessed, I'm on a mission for Sonic Advance stuffs. So, my current project, StH:DX, will be less of a priority until I've found what I'm looking for or give up. Don't worry, it's still going to be continued.
EDIT: Changed the topic title, as a pre-emptive strike as to what I'll release in the coming days.
EDIT2: I'll release my stuff now, cause I'm moving on. That was rather quick, wasn't it?
EDIT3: Don't try downloading that thing, the board transition screwed up the file.
EDIT4: Upload removed, new link added.
EDIT5: Url fixed, it's been broken for about 2 months. =P Thanks Scarred Sun.
Sonic Advance Hacking Notes
I warn you, these notes are a bit shoddy. They're good enough for now. =P
