I'm having this problem that i can't find the solution. I'm using a 3DS XL, with patch version 4.3.0-10U. My dstwo is up to date, and has the latest version. Here's what happens: I can play GBA games perfectly, just fine. I used to be at least able do open DS_GAME, and see my game files there (in this case new super mario bros. and time hollow). One day, i decided not to play GBA games for some minutes, and launched new super mario bros. I launched DS_GAME just fne, selected new super mario bros and loaded it. The game menu appeared, just fine, but I had to have breakfast and quitted. I went back to the dstwo menu, pressed home button, went back to the 3ds home, and then turned off. When i came back to play one more, the moment I pressed DS_GAME, the Nintendo logo from mario appeared, like if the game was being launched, and then all became black. I waited, for like 10 minutes just to be sure. It was frozen. I didn't even had the chance to select the game. I turned the system off, reloaded the card, and it happened the next 3 times I tried it. I checked the filesystem on my PC, and it hac created a .DTC and a .SAV files under the game's name. I deleted the .DTC and everything went fine, I could select games again. But when I selected mario , it froze again... Is it just this rom's problem? Is this a common thing? What can I do about it? Thanks in advance.
