Just setting up my sons ds using TTDS. Things working good for a week or so. Today I decided to remove the games and then put them back on in the order I'd like them to be on the TTDS menu. After doing that, I now have duplicates of all the games. The dupes have the same icon of the original game but the file is called Di3.nds etc, etc. I've removed all files including TT menu, moonshell and games and starter over. No luck. Dupes still there. Any ideas? Ok. Just reformatted the microsd and added games. All is well. Now, if I delete a game on the micro sd, it shows up on the ds as a Dix.nds file. It still plays. Is the game being store on the ds or on the TTDS card?
