Schumi's FAQ said:
7. I can't load any games? I get some sort of unable to read card error? The data could not be accessed. Turn of the power and reinsert the DS card? Some sort of strange japanese/spanish/any other language text when I try to load any DS game? Correct savetype for my game? Cartridge not found?
Versions before 2.6a do not have an autodetect savetype function and therefore need to be set manually in 'Options->Emulation Setup->NDS cartidge backup media' (...)
LMAO.you didn't heed the warning about playing thsi game D:
Tingles Rose Rupee Land
Warning, this game may instigate incidences of homosexuality among players, and cause those who would kill themselves before turning to do themselves in.
Other then that, its probably using a backup format thats not supported by no$gba
