Hi all, Hadn't seen any answers about this. Just got two DSTTs from DX. One seems to be working swimmingly; the other is wonky. Biggest recurring issue is games flipping out when attempting to save--the game will say the cart's not there, or the game will freeze. Happens with New Super Mario Bros and Diddy Kong Racing in particular. Other games go straight to white screen when trying to load. Firmware is official 1.17, but I checked the model and the checking software says it's legit, so I don't think it's a fake-killer issue, as some games load fine. It tested fine before I gave the card to my friend, and I even updated the USRCHEAT.DAT so she could play Chrono Trigger (initial load of that game worked fine, not sure if it wonks out later), so I dunno what gives. Wonky memory card? Need to remove the fake-killer firmware? As simple as a clean format and restart? Thanks! EDIT: OH! Also, what's the best way to shrink files? I was surprised when zipped NDS files didn't load, and I know other cards can auto-trim files, but I don't know how to do that manually. Thanks for any help.
