We start the tournaments with 4 Player Free4All Prerounds though and I thought it'd be cool to build a ROM with some other custom stages that I've found on the Internet and that are maybe a bit bigger than these and therefore more suitable for 4 Player games. Most other mods only have one modified stage though, can you tell me anything about how you managed to change so many? When I try replacing stages myself my Emulator crashes every time. I've read something about HEX modifying somewhere, honestly not quite sure what that means though. Is there any documentation you have found as a basis for your mod? Thank you once again for the time and effort you put into this!
