hopefully, this isn't as restrictive with phones as sonic mania. works fine for me. compiled and booted with no errors. I changed the name from RSDKv3 to Sonic CD. I would change the icons as well, but I'm not very good with photoshop. the res zip file is the icons, if someone wants to help me out? for the main game, you need the rsdkv3 file in /RSDK/v3 as data.rsdk , which I can't supply, because it's copyrighted.
