People say that there is lagg and whatnot in the emulators, and if you put on sound, it's even worse.

SNES works perfectly with sound on my Sprint Touch Pro. I use the built in keyboard for all my buttons. The only problem, is no matter what I do, Up is always left, left is always down, down is left, and right is down.

I use JD's custom rom. Works well, Speeds up the phone a bit too (and makes it so the emulators don't lagg).
Downside: I don't know if it's the rom, or if my sprint screwed something up, but I can only text to AT&T, I can't text to T-mobile, or Verizon.

The keyboard doesn't work originally with emulators, the keyboard views as only like 3 or 4 different buttons in total(Even though it has well over 30, so you can't assign keys to it.
It's caused by the T9.

I can't remember where, but you can get a little cab file on Xda somewhere that disables the T9 support, and that will allow you to use all the hardware buttons on the keyboard. Downside: You can't use the symbol menu anymore ("sym" key to the left of the space bar gets disabled). Pisses me off.

Alternatively, you can get a program called Keyboard for touch pro. That just lets you turn off the T9 with a button, and you can put it back on later. however, If you have CE-Star on your phone(Japanese/chinese Input), like myself, It won't work. So your only choice if you want to keep CE-Star but still use the keyboard for emulators, is to use the cab that kills T9, unfortunately.
