Pokemon Mystery Dungeon: Explorers of Sky saving problem

I have the supercard and when I want to save, it says that the save failed is there anyway to solve the problem?

 

Have you got the latest firmware.

 

Or, if you use cheats, those cheats can corrupt the safe file.

it happend with me while playing runefactory 2
try playing it without cheats and see if that fixes it.
otherwise you'l have to wait for a fixed cheat library file

 

yea im having the same problem and it happens before i used my cheats

 

i don't know about that card, but a suggestion may be to make a save file by just copying another one and renaming it "rom-name.sav"....that worked for me on my ez vi...
