Ah I see, thanks for the link, that's a pretty thorough explanation - and a lot of work.
Whenever I have the time I'll cfw my "spare" PS3 and try the dumping method. Though I read I could also use backups to extract the games from? That seems a little less work, I might can do this soon. :)
You're welcome, glad I could help.
You mean the .pkg? Yeah you can, you can use an ISO or the typical PS3 game folder to launch a game, that is yours to decide :)
