Can't save on Digimon Dawn.

When I try and save it just says "Could not save data. Please power off and re-insert the Game Card." Then when I check the battery folder, there's a .sav file. ??? Can anyone tell me what's goin on?By the way, i'm using the No$gba emulator.

Make sure you are using no$gba 2.6aOr you can try to change the save type (but 2.6a adds an Auto detect setting).

this one is easy fix open up your no$gba then try to play that game when it come up with the error go to "options" then "emulation options"
go down to "NDS cartridge backup media" click the down arrow and try to run it as "EEPROM 64KBytes" (most games run on this suck as spectrobes and new mario as others like the new pokemon games run on FLASH 512k) once u have "EEPROM 64KBytes" seleted click "ok" then go to "file" then click "reset cartridge" it should play if not try running it as the other backup medias until one worksu will have to save "in game" when u save with the no$gba it crashes
