Do those discs have ISO files on them? If so I suggest you delete them because they are highly illegal and hurt the game industry not to mention they are against the rules to talk about here. It would be best not to use the files on those cds and just download your homebrew games and emulators from here- http://psp-news.dcemu.co.uk/ (look on the bar on the left hand side). To run homebrew on your psp. First create a folder callled "PSP" on your memory stick. Then inside that "PSP" folder create another folder called "GAME". When you download homebrew it should be in two folders one with the name of the homebrew, and one with the name of the homebrew and a % on the end. For example "homebrew" and "homebrew%". Put these two folders in the "GAME" folder on your memory stick. Then just run the homebrew on the psp.
