1. we could play every old gen emu like n64 and saturn,but still they have not been released, Saturn probably never. 2.For Duplex PSN games u don't need backup managers like MultiMan od Rogero,PSN games run from XMB just like when u download something from PSN,so u could probably be able to play them but that is still unknown,untill we see 3.73 JB and what can be done. BM will not run on 3.73 JB *for now* so that is why people want to know if Duplex PSN games will work on 3.73 3.for this exploit u really don't need working blue ray so yes u can use it..but would be best if u fix that in future
