I'm having some issues of my own. I installed the Homebrew Channel and a few emulators last night. One of them was Snes9x GX. I played a few roms and everything checked out. Today, I went to go play some more, and noticed one of my rom folders seemed to be corrupted.
I copy-pasted my roms within their original folders from my PC. I have so many it was easier for me to arrange them in folders, so it looks something like this on my SD card:
roms
--Action
--Adventure
--Superscope
--Puzzle
--RPG
...and so on. You get the idea. Well, yesterday I was playing some RPGs. One of them was actually the Dejap Tales of Phantasia, which may have had something to do with it, but I didn't move any .ips files over with my roms. Today, I loaded the RPG folder, and all the roms were gone, replaced with what appeared to be garbage at first glance. I put the SD card back into my computer and got this:
The first thing I did was show all the hidden files, and there were several. Then I tried to delete them all so I could put my RPG roms in there, sans a few which may have caused problems (patched ones such as the Dejap). However, I got an error saying it couldn't read from the source file or disc. I tried to delete the whole folder and got the same error message, saying I couldn't delete the files.
But as I said earlier, I previously had no problem loading and playing roms from the RPG folder. The only thing I can think that I did differently was delete some of the files I felt unnecessary at this point from the root (files I used to install the HB Channel). My root now looks like this, if anyone is wondering:
So now I can't delete these files and don't know what happened with my SD card. Can anyone help me out?
