ISO/CSO games show up corrupted. Tried everything.

Now, Everything works, except ISO/CSO games.

Yes, they are is ms0:/ISO/, but they just won't run.

Every zip I've tried works, but ISO/CSO's just don't work at all.

I don't have a UMD game inserted, but the drive tray is literally melted onto the drive.

Also, my SDtoMS adapter has cracks on it. Although it shouldn't be a problem though, as I've already mentions, zip games work.

My PSP software is "6.61 PROMOD-C2p∞".

This is a PSP-3000.
