Hacking trouble playing any games on sc minisd

[nuhbiwan79]

hi there, i have a supercard minisd fw 1.7 convertsoftware (2.55,2.56,2.57,2.58)
my ndsl has flashme v7 on it and a gba sp.
problem:
i can´t get a single gba game to work with the sc.
ds games work very good.
when i start a gba game, i can play for a few minutes, then game freezes with graphic glitches and a stange sound appears (repeating all the time). i tried a nokia 128mb minisd card and a extrememory 2gb 133x minisd card. i also tried to disable all options but the save and save patch options in the convert software. nothing helps. when i check the sc by holding l+r during booting, it says everything is ok.can anybody help?

tried games: ff IV, ff V, zelda (both), super mario.
like i said, all nds games work perfectly.

any ideas what might be wrong? the card is NOT fake. same errors on a gba sp.

ps:in zelda minish cap the sound goes on, but the screen freezes

did you do the selftest by holding both triggers on startup?

 

[nuhbiwan79]

yes, of course. the test result is, that everything is ok-

sram ok
sdram ok
flash id ok
flash ok
test sd/mmc ok
not find testfile
Now SC Version:1.70

is it possible, that my mini-sd card is junk?
i use a 128mb nokia and a 2gb extrememory 133x mini-sd card.
like i said, nds games work perfectly.
i thought it could be that i used bad dumps, but same when i get the games elsewhere!
