After many hours of debugging of our OUYA port I found the very sneaky bug that’s been bugging (ha!) me for the whole time. As it turns out the Tegra 3 (which is the core used by OUYA) can only handle textures of sizes that are a power of 2 (there are still GPUs that can’t handle arbitrarily sized textures… go figure). Anyhow, Nifty is now running on the OUYA (the startscreen that is) although the scaling up to 1080p isn’t yet working as expected…
A strange little box arrived in a package two days ago… I wonder what it could mean…
Porting Nifty to Android (and later OUYA) is making progress and quite a few things work already. Some effect shaders as well as shading and loading of models are already working (even better than before!). There’s still a lot to do / fix / improve but I’m confident that the development of game content can be continued soon. 
After hours of refactoring and method-matching, the android port of Nifty has no more errors (meaning no compile-time errors; it’s far away from being playable)!
