Well, as posted in the past Site News CJPC has been able to get PS3 retail back-ups working on his Debug console... but the process wasn't all 'neat and clean' to launch them after unpacking and patching.
So basically what he did was made a "Backup Launcher" frontend with a menu so you can select from games on the PS3 HDD and run them. Of course this is only on a Debug PS3, but still it's damn
cool to see!
The joint project I mentioned above is geared towards retail PS3 consoles, so this way regular people like you and me can get involved, versus just reading about what the PS3 Devs are doing periodically.
