NES Emulator for PS3.

[Mase]

you will not regret hacking your PSP. It takes on a whole new life with CFW.

Customize your XMB
Customize your GameBoot
Play your PSP games from your MS - not only can you store multiple games on your MS, but it helps improve loading times.
Play PSX games from your MS - PSN and Custom PSX games
Play Homebrew Games - including emulators
the list goes on...

You can always go back to OFW if you find you don't like CFW.

Wow, I think I have to hack mine now haha.. Although I am not too handy when it comes to things like that, so I may have to find someone who is...

Just to mention, if anyone is having problems getting the BD-J NES stuff to work:

You can't run it from a memory card for some reason, it has to be a USB flash drive (or a memory card connected to a USB card reader).

Some restriction on what BD-J can read.
