I've only been doing this for about a week now, downgraded my psp to FW 1.5, downloaded Tekken DR and am running Devhook without a problem. My question is this, I downloaded 300, but the game isnt an ISO. When I passed it through WinRAR, it put a file called "PSY 300" > "PSP_GAME" and "UMD DATA" > (in the psp game folder) "SYSDIR" and "USRDIR" How to I combine all of these to create a ISO or CSO? I've surfed the forums but cant seem to find anything. I got the same result with MOH; Heroes. Any help would be greatly appreciated.
