ok well here we are. There are some other threads around, but they have been quite as there wasn't much more news streaming in.
Here is what we have
CocoonJS will be supporting Ouya. This is the currently ideal course, but Ludie isn't exactly speedy with it's updates. Infact WebGL was said to be out soon; which was a few weeks ago :(.. but it is coming if you don't mind waiting.
Psema4 who you can find on the developer Ouya forums. Has managed to get a wrapper actively working with the Ouya. This includes the controllers. It does work right now as I understand it. it's not a fast wrapper, in fact its' probably just the default speed for performance, but if you don't do anything fancy. it's probably enough to run most non intensive graphical games. He is working to get the entire Chrome Kit running. So that can lead to a lot of possibilities.
Jenpop who is active here under another name. Also worked on a wrapper, but unfortunately there doesn't seem to be a public running version.
Pender Android
This is all ready to go short of the controller and Ouya IAP. However, as Pender Android is written in Java it shuold be simple to get the controller going. In fact i was thinking of just mixing Psema4 java code into Pender.
Game Closure
Same state as Pender, almost ready to go, but you will have to build the bridge between the language. However, there is more overhead as GC uses C++ and a middle language of Game Closure known as Barista.
Right now I'm working on an Oyua game. I am going to take more depth once it's ready to be ported. I'll update or put up a tutorial on how to get a game on to the ouya when I'm done. If some one else hasn't by then.
Also I got my Ouya today. Bomb Squad is awesome :)
