I followed exactly the instructions I found here: http://www.youtube.com/watch?v=-MP3b8xuY_c Moonshell 2.09 install guide for DSTT/i with YSMENU When I boot, I can see the Moonshell2 menu, I can browse the apps but when I start a game I just get a white screen in my top display and a black screen in my bottom display. I even tried using "TTCARD IO Library (SDHC)" instead of "TTCARD IO Library" in the DLDI patcher, didn't work. It didn't even boot. My MicroSD is a 2GB flashcard, on FAT. I am running my games from the root folder, I don't know if that is a problem? I am also patching moonshl2.nds, but there is also a moonshl2_DirectBoot.nds that I haven't tried but according to the instructions it should work with moonshl2.nds. If you have any other ideas I could try to make things work, it would be really appreciated. Thanks! Edit: fixed youtube link description.
