I posted this on another forum, but I figure I'll see what you guys can make of it. Earlier today I tried playing this multiplayer against my friend, who used my cartridge while I used a trimmed rom on my Cyclo. I used the CycloDS Evo Tools trimmer, which supposedly doesn't affect multiplayer compatibility. Whenever the game was about to start, it would suddenly disconnect. I've never had this happen with another game using trimmed roms. I've heard that it can happen sometimes, but also read on this board that the Evo Tools trimmer shouldn't do that. So I'm not sure of the cause really, but I'll throw this out there to see if anybody knows why this may have happened and how I can play multiplayer. I'll try using a non-trimmed rom, but it'll be a while before I have the chance to try it out on multiplayer again. I also have the latest non-beta firmware (1.4), and I don't use any of the advanced features like real-time save or cheats or anything. Anybody know what's up? Does the multiplayer work on your cards?
