There will be a Resident Evil RPG and I managed to find some sprites.
Ada Wong (RE2 costume and RE4 costume)
Chris Redfield (Two versions)
Albert Wesker (Two versions)
Jill Valentine (RE1 costume and RE3 costume)
Licker (From RE2)
Leon Kennedy (RE2 costume and RE4 costume)
Stinger (From RE Zero)
Unfortunately, that's all I can find and since there's already a resident evil rpg set in the RE1 era, I'll be setting mine between RE2 and RE3 coz of the sprites I found, let me know what u think.
Here's the link the author's website www.residentevilrpg.rg.com.br/ so u can download the RE RPG, but the site is in foreign language and the RE RPG game is based off the PSone game, not the gamecube remake. U'll notice it by the items and the puzzles. Enjoy
