I'm thinking of hacking my PS3, and I just want to know what hacking it will do. My main questions are: I have an old PS3 slim, and can do a factory reset to get to a hopefully hackable version. 1) Will hacking brick my system? 2) Can I play PS3 game backups? 3) Can I play PS2 games? If so, only the ones on PSN? 4) Can I play any games on the PSN?
