Every game I try to play *Newer games* has the same "cannot load save data" or w/e it's called issue. I've tried Arm7 patching all of them, multiple times with different games, nothing. I even made sure I had the newest firmware (newest I've found is 1.14), still nothing. The last game I tried this with was Metal Slug 7, but I tried it on Wall-E (I was bored and wanted to see if it worked lol). What in the world do I do to make this stuff work
