Run "gw3ds.exe scan x:" (where "x:" is the driveletter of your GW3DS microSD card) from a command prompt window to scan for problems. Run "gw3ds.exe fix x:" to fix fragmentation errors and missing game icons. You receive a fragmentation error when the rom file has more than 32 fragments. You receive a fragmentation error when the rom file occupies either of the last two clusters on an exFAT partition. You don't see all game icons if the root directory entry is fragmented. https://dl.dropboxusercontent.com/u/94421767/gw3ds_ver_12.zip https://dl.dropboxusercontent.com/u/94421767/gw3ds_ver_10.zip EDIT: Avast seems to think that my program is infected with malware. I can assure you that it contains no malware. I wrote and compiled the program myself. I reported the false positive to Avast so hopefully they will fix it in their next virus database update.
