I read every thread before making this one and couldn't find my answer.
I switched to ARK from T_N's CEF after hearing it's better but when I switched, something went wrong and I had to format the memory card and start from the beginning. So my CSO's and homebrew were deleted. I can easily add homebrew using VITA FTP but I used VITA FTP to make an ISO folder and put all of my CSO on it and none of them worked. All of them were shown as corrupt but they all worked on CEF. I also heard in yMenu it doesn't matter where they are so I put it in ms0://PSP/GAME
and even in the SAVEDATA like you would for CEF but nothing worked.
Can anyone help me fix this problem?? I'm a little lost. Thank you in advance.
