Q: Can i play games that are in rar format or iso/cso but in a folder? Will they still work? Or the only way is to drop cso/iso format inside the psp ISO folder? Any other ways?
A: you cant play anything in RAR format as rar is just a directory to store files in open the rar format using winrar or winzip then click and either drag or copy/paste the iso/cso folder into the ISO folder on the root of your memory stick im assuming you are on custom firmware...yes??
