I just got Pandora's Battery to work and downgraded my 3.52 PSP to 1.5. Awesome! Now I want to play ISOs on my PSP. I just downloaded this Pinball ISO and Devhook I got from Igizmore, maybe you know him. Devhook is now installed into my PSP. Now, how do I get that pinball ISO on my PSP? It is a WinRAR archive now. Am I supposed to extract that to get those 2 files, PSP_GAME and UMD_DATA.BIN. or do I just put the WinRAR Archive in the ISO folder on the Root of my PSP? After the ISO is on my PSP, how do I play it using Devhook? I need step by step instructions. Thanks a lot.
