Wouldn't it be great if you could use your PS3's hard drive to store your games? Capcom recently claimed that by loading a chunk of data from Devil May Cry 4, they managed to significantly decrease load times, so it could prove very benificial. Well a group of hackers have managed to load retail games on their PS3.
While this does seem pretty cool, it's by no means something I would recommend doing. Just think of how large your PS3 games are, single-layer Blu-ray discs can hold up to 25GB. Your drive would be full in no time.
There's also one more small hitch with this hack, you have to have a PS3 Test unit, not a retail PS3. What's the difference? A Test unit is used by game developers and cannot actually play retail games. The hack does, however, allow retail games to be played on the PS3 Test. If you're one of the few people that actually owns one of these, then you're in luck.
