I had strange problem, it occurs from time to time, on my acekard rpg, and I dont know is it fault of microsd or acekard. I was planning yesterday to launch geometry wars galaxies but discovered that save, that existed couple days ago, now is gone, same thing occured with micro machines game . I checked microsd and saves were gone, bot not all saves only those two. Now Im worrying , could it be that acekard system is deleting saves (I done one update of firmware, but copyied savelistex.bin , and every other games on nand flash and microsd were fine). Maybe saves were gone due to coruption of microsd (once I tried to open my games folder with dsorganize, but it hainged, so i restarted my ds, maybe this was it, but how only saves could be gone and every game would be fine, I dont know). Has anybody encountered same save problem ?
