How to convert PSP_GAME to ISO CSO

This is will teach you how to convert PSP_GAME and UMD_DATA files to a ISO then to a CSO.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
If you are trying to play these games on your memory stick, PLEASE have custom firmware on your psp otherwise you will just get an error. For those who don't know what custom firmware is, it's a hack on the Sony PSP that allows you to play ISO, Homebrew on your memory stick and you can get custom themes and many more features.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

UMDGEN v4.00

eh... can u help me... my psp version is version 5.50.... i go to every shop but they say they can't change... why??? plz reply

[pspslim2002]

@guzzlerbear94 Is it normaly version 5.50? Not Custom Firmware? If it is just normal firmware and you are asking shops like EB Games to change it over. They will NOT change it because 2 reasons.

1) The shop will loose money because you have downloaded their games

2) That could be considered illegal.

Please respond! i did everything that you did even the YACC compressor

but with every game i put in the iso file the game is there when you press x at its just shows blank screen with nothing happening whats wrong?

(My PSP version is 5.50 GEN D3 if that is required for you to think whats wrong)

[pspslim2002]

@lolagepwnageownge Yeh..... The thing is I dont use a PSP now, so I don't know what the problem is, It might just be something wrong with the ISO file.
