Apparently there's no drm on Bully for Android. I pulled the apk off of my phone with ES File Explorer as well as the obb files, tested it on my Shield TV, then tried it on the OUYA. Worked for both. I bet it would work on the Forge as well.

On the OUYA there were graphical glitches on some of the signs, the framerate's a little low, and there seemed to be a little controller lag. The controls themselves are fine, but the buttons are set up for an xbox controller. A double tap on the touchpad replaces the start button.

Here's a video if you need help sideloading. Footage taken from the Shield TV, not the OUYA.
