I just installed the games again, but for future reference how would I load the the NAND backup?Yes you can just install the games again. When you made the NAND backup you should have copied it to a safe place. If you left it on your SD card it might be in gmout (I think).
Also can anyone explain to me why freeshop keeps crashing every now and then? Something about unexpected arms dump? It's happened several times and then I forget which games I'm currently downloading. Thanks!
