I'v downloaded the game fifa street 2 CFW......
After copying the .cso file in the umd directory and then selecting it from the options "load UMD", it says.... "the game has been encryted by the soft. publisher.. it has to be decrypted by a real psp" .... the same was for FFIV complete collection and Football Manager Handheld 2011.
plz help me....
I'm using jpcsp 0.6 the latest one....
