Hacking Supercard mini sd Sram solution?

[DeShelly]

Hey guys.. i buy couple of days ago a supercard and i find mini sd adapter and i have 500mb sd and i format the sd on Fat, and i put games with supercard software.. but my problem is this: Why my sram doesnt work ? i press L+R and i see its gaves me this results: Test SRAMSRAM error: 0105 CPLD error .. As i read on forum the Sram is a some kind of battery that keeps the saves alive somehow? but the supercard sram dont have much lifetime than official srams .. and i think this is normal because the official srams keeps 1 save from 1 game and the supercards sram keeps many games saves.. so.. is any solution anyway to save? i need to change sram from a original game? or i need to buy a other flashcard? or i need to change sd? (its impossible to find a minisd this days), or roms are the problem somehow? (sry for my bad english)

Just open it and check the battery with a voltmeter
