Yup, thats right, my TTDS is killing itself. It has been working fine since I got it until I tried adding DSOrganize, which is now gone along with all files associated with it(I deleted it because the touch screen refused to work). My larger ROMs freeze after about half a second of loading from TTMenu, Ive tried loading them with YSMenu and they work fine other than my sav files dont work(chances are this is my own stupid fault for trying to be 'organized' and moving them from the root to a new folder). On top of this moonshell2(beta 12 I think) freezes up upon loading through TTMenu or YSMenu, this just started today, a few days after my ROMs died. Ive run the TTChecker or whatever its call repeatedly and it says the card is real every time. Here are the details on my SD Card: Brand: Kingston Size: 1GB Currently used space(after removing YSMenu and DSO): 594MB Here is logbuf.txt from moonshell also: CODEactive_interface->ul_Features= 0x23.

Please refer [/moonshl2/logbuf.txt] this is followed by several lines of dashes is there anyway to fix this without a full reformat?
