But sometimes the color seems washed out, only when using the frame buffer though (aka fullscreen).

Wow, much better. Thanks a lot for this great update! Pokemon's colors now render correctly...

I can save game on Zelda!! any trick?

Oh, really? That's pretty strange, there should be no reason for such behaviour. There is reason for it using Xsp and X (due to many layers and asynchronous behaviour of X) but with direct update ioctl the window coordinates and scaling should be specific per each update. There should be no state stored in kernel between updates, everything comes in omapfb_update_window structure when ioctl is called including color mode. Looks like kernel bug or some side effect. I'll check it out. That would be pretty unfortunate.

Mplayer handles it fine both in fullscreen and windowed mode, though. It does direct access also in windowed mode and bringing up power key menu or any other menu (statusbar,..) works fine except messing up window of mplayer (which is to be expected).

My only criticism would be that figuring out where the controls are on the touch screen is a bit of a guessing game (for VGBA).

It looks to me like this setting is stored somewhere in OMAP hw registers rather than in the kernel. It is possible that when the driver receives an omapfb_update_window structure that does not specify scaling, it does not try to reset previously set scaling settings. Then it is a bug in the driver.
