Hacking something messed up when I was downloading emulator

[sand_owo]

so I just finished getting CFW on my 3ds. I decided it would be nice to have an emulator. so I got mgba cia and I think I might have broken something when I tried to make a folder for rom. now I don't have the theme and I now have presents that have no text and open a black icon. when I try to open it it gives an error

Copy everything off your card, reformat it in FAT32 + 32 KB cluster size (Windows File Explorer -or- guiformat), and full Write + Verify the empty card with H2testw.

Hit up your local library's computer (may or may not have USB privileges), a buddy that does have a PC (for Mac you'll test with F3X), or if you're brazen enough, do it at Best Buy while you spend time surfing the Internet and chatting with the sales rep (try not to show you inserted the card in one their laptops).

uh, no.

uh, no.

Too stubborn to make sure your SD card isn't fake or dying, eh?

Well, enjoy continually corrupting your data.

sounds like a fake SD card to me, the advice you were given is the best you can hope for, maybe you should have a little more gratitude for people going out of their way to help

last piece of advice you can get is maybe test the SD card in a mobile phone or something, i would imagine someone has made a H2testW-esque app for android, other than that you can try reformatting the SD and try installing stuff again, but if i had to bet its a shitty fake SD card and your data will all corrupt again as soon as you start to fill the SD card and the card starts overwriting the existing data with garbage which is what produces the effect your experiencing here

Would you happen to care if your replacement SD card also happens to be fake?

Flash memory doesn't last forever. If not fake, then failing as the NAND cells wear out over time.
