I was wondering if anyone knows a DS rom patching program I can use to get a few games saving properly on my R4i card. Most games I've played work perfectly but Contra 4, Mario vs. Donkey Kong 2, and Mario vs. Donkey Kong: Mini-Land Mayhem won't save properly. Every time I boot them up, they say they're creating a new save file, and stuff doesn't stay saved in the games. I can upload pictures later to show what exactly is going on. It's annoying because it's only with these games.
If anyone can point me in the right direction or give some suggestions that'd be much appreciated. Thanks!
