ok when i go on games and choose which nds rom i want to pick it usually has icons right? well for some of my games it does and most of them its just a bunch of purple pixels or just plain black. the games that dont have icons messed up work fine but the ones that are messed up wont boot.

im getting kinda worriied

 

i was using 2.8 but i updated with your 2.9 i your sig and its working again, thank you very much!

 

This happened to me recently. Most of my stuff got corrupted and I couldn't even delete it through the computer.

Plug your G6 up to the computer and try to rescue all the roms/save files you can, then format it through the DS. You should also go get the 3.1 firmware to put on it afterward.
