Will the PSP Dumper work for Cfw 3.80 m33?
Don’t use PSP Dumper, it’ll just be a waste of your time. Just go into the main PSP folder when you have USB mode changed to UMD Disc. (You can do this by pressing SELECT and going down to USB DEVICE and pressing either left or right until it says UMD Disc. You do have to enable the VSH menu to do so, and you can enable it by holding the R button while turning on the PSP, going to “Configuration,” and then scroll down to “Use VshMenu” and press X to enable it.) You basically go to “My Computer” and then select UMD9382 (or whatever it would be called) and go into the folder. There should be one item in the folder called something like UMD9660 and you can just drag that into another folder. You can then use PSP ISO Compressor v1.4 to compress it to a CSO (always use the first compression, because anything above that won’t make much of a difference other than making games take longer to load).
