Thanks for the advice though that wasn't really an answer to my question..
There are several games I want to do this for at the moment and I'm not really trying to buy all of them. I really just want to know and be able to do this at this point because of technical aspect to it rather than to complete my collection. The main game I am currently trying to do this for is Rez (PAL) and if I purchased the PAL copy I'd still like to be able to make it NTSC self-bootable. Been digging around for days and don't feel like giving up yet.. If anyone has ever done this or has the skills to understand how I can go about it please do chime in. It would be great information for anyone and everyone here in the forum.
If I end up figuring it out myself I'll be sure to let you guys know. Thanks!
