Just a heads up, N64oid is available through the SlideMe Market, it's 4.99 but it works great. Touch-only phones, it will give the keypad on the screen, but it will install Bluez IME if you so choose if you wanted to connect a bluetooth controller for the droids such as the iControlPad, Zeemote, or even a Wiimote. I'm currently getting them to create a driver for the Magic-Pro BT Touch2, awesome little bluetooth keypad with a touchpad made for PCs and smartphones/tablets.
As for a PS emulator, still looking for a decent one, will keep posted if one comes along..
Cheers
