Dino Crisis 2 was released this week in the PSN. Curiously, it is the first PSOne game that don't need activation to work. Just installing the .pkg file is enough to make the game run.
Could this open the doors for a method that it will make it possible to inject and run others games, like what happens with the PSP?
I'm not sure if it's allowed to post a link for this game, but if you search for it's file name, you may find it.
