If you haven't looked into Emulators I highly suggest it. Most of them work very well on modern Android devices and with a variety of controllers as well. Personally I like using my sixaxis, but I'm looking forward to the 8-bitty when that comes out. In case anyone didn't know you can get most console emulators for free (legally) using the following links. These are projects that were removed from the market for one reason or another and were converted to free due to it. SNES9x EX was always free.
Here's a link to Yongzh's Emus which are mostly free (All but N64):

And my favorite SNES Emu SNES9x EX which was removed from the market, but available Downloads - Ex Plus Alpha
Here's a couple vids I made using SNES9x EX
