Help no$gba crashed when I tried to load my game?
If you are running no$gba through your DS firmware (firmware.bin present in in no$gba’s folder and ‘Options->Emulation Setup->Reset/Startup Entrypoint dropdown set to GBA BIOS (Nintendo Logo)’) then the game has to be encrypted using either eNDryptS or NDStool (which may have problems working on Vista). Note however that most games no longer require being loaded through the firmware as no$gba now has sufficient emulation of it so ‘Options->Emulation Setup->Reset/Startup Entrypoint’ dropdown should be set to ‘Start Cartidge directly’ to avoid the need for firmware and encryption. Alternatively try deleting no$gba.ini and allow no$gba to create a new one after which you will then have to setup no$gba again, but the corruption should be gone.
