Its generally agreed that if we can get the powervr engine up and running we can discuss details later, there are many powerful things you can do once you have the ability to to transformation and lighting. it doesnt actually matter if its fullscreen or not.

Games people dont care about lower resolution;
I challenge most people to be able to tell the difference between 640*480 and 800*480 (liqbase can show you)

I know the hardware is capable and I hope someone can manage to advance this.
