Cool project.
I would like to know more about how you managed dramatic fps increase.
Did you managed to find out how to draw pixels faster?

The fps increase is only theoretical so far, I am still preparing a test app. Basically the framework uses atlasing, which is where there are multiple images in the same image file, similar to a sprite sheet. The reason it should be faster is that

there are less rendering state changes by binding once, it can be faster to bind one large texture once than to bind many smaller textures as they are drawn.
(wiki). With that being said, awhile ago I found out that there are image size limitations for the Zen, which if I remember correctly are only imposed on the y axis.

Version 1.1 is released, check the top post for the new download. The app now uses a new version of the framework (with an automatic texture packing parser).

Version 1.11 released, over 200 lines of code have been removed. All of the screens now use a built in ui library that handles buttons automatically.
