So I got an R4i card to put all my games on and have had success with all of the games working except for a few. The most pressing are the Mario vs. Donkey Kong games, MvDK 2: March of the Minis and MvDK: Mini-Land Mayhem. When I boot them up, they work totally fine and it says that it creates a save file, but when I go back to the directory of games, both of them show up as not having a save file made yet, as if I'd never booted them up. They won't hold a save at all. When I look on the microSD card, the save files start piling up each time I try to boot up the games and are named "MARIO VS DO.SAV" on both of them. Does anybody have an idea how to fix this and get the games working on my DSi? I'm using the official firmware and everything else works perfectly so I don't know what to do, short of carrying around the actual carts for those games around (which defeats the point of the card). Thanks.
