Zelda Phantom HourGlass saving problem on NDS

Ok, i just downloaded 1514_-_The_Legend_of_Zelda_Phantom_Hourglass__E__XMS_ for NDS. Please note im not using a emulation, im using a chip called N Card. Now when i play it, its great. So im playing and i gotta go so i save and quit. I turn my DS of and 1hour later return to play some more, sadly it claims both saving slots (1+2 even though i used 1) are corrupted. Now thats odd :(
Any help will be greatly apprectiated.

thanks for all your insightful posts :(

you need to be patient, people have lives, and some people need to sleep. The N card is actually one of the less compatible flashcarts out there, I don't know if patching roms helps or not, unfortunately, someone else with an N card would have to answer that.

I fixed it thanks to another site, but thanks for the reply loonnylion
