I just installed 3.52 M33-4, and I successfully played a .cso game iso on it, but I have a few questions:
1) The System info in my PSP states '3.52 M33,' not '3.52 M33-4,' despite the fact that I successfully ran the M33-4 update. Is this normal?
2) The Game>Memory Card list is full of hundreds of Corrupt Files I must scroll through for about 10 seconds before I can get to the .cso game iso at the end of the list. I tried to hide the Corrupt Files using the Recovery Options option of enabling the hiding of Corrupt Files in the Game folder, but it didn't work. Is there any way I can safely hide or delete whatever files these are?
3) Lastly, the first time I turned the PSP on after turning it off after playing the .cso game iso, it stayed on a black screen, and I couldn't turn it off. The Power light stayed green, and raising the Power slider didn't do anything. I located and removed the battery to force the PSP off, put it back in, and the PSP resumed normal operations. However, to stay on the safe side, I'd like to know if there's a reason it did that?
