Hi guys! I got a question regarding Sonic 2 SMS and swapping around the zone order. I attempted to get in contact with Ravenfreak about it, but I haven't got a response yet, so I decided to ask the other 8-bit ROM Hackers here. I swapped around GHZ with UGZ. Everything but the tileset mapping, zone/act screen palette and music is correct. I don't understand how the mapping isn't there, but the tileset is, considering both are defined in the level_headers.asm file correctly. Is there something in s2.asm that I missed in regards to mapping? The music is something I can't figure out either, what do I need to do to fix that? Problem solved.
