Hi, I just wanted to ask about rom compatibility with this cart and describe my problem. Well a few minutes ago I just turned on my Dsi Xl and started up Chibi Robo: park patrol (badass game btw) and it's loading the game as if I'm starting up for the first time. It's asking me to start a new game .. F***!... I mean I logged at least eight hours or so within the past few days and now my save is gone. I'm pretty pissed because I thought this cart was supposed to be reliable. I started(on my cart) Disgaea DS to make sure that that save wasn't corrupted and it did the same thing asking me to start a new game having previously logged about 3 hrs into the game. I have played these games through multiple sessions and now out of the blue the saves are missing/corrupt. Also I've checked a few other games on my cart and their saves remain intact. So is there any rom compatibility issues? I have a kingston 4gb card with 34 games on the card most are rpgs which is why I need to know what going on. Thanks for any assistance.
