Console Emulators, nitoTV or XBMC?

Does anyone know how to install console emulators through nitoTV or XBMC in the latest version (5.0)?

UPDATE: After a pile of Google searches it appears emulators through nitoTV are only supported on the AppleTV1.

There are emulator plugins for XBMC, but all the ones I’ve found won’t work on the AppleTV. Has anyone managed to get NES/SNES emulators to work on the AppleTV through any 3rd party plugin?

Bumping since editing a post doesn’t move it to the top.
