Oh hmm I never knew of course. :/

I guess so. As usual I don't have the time to contribute on such
a major project myself either (or the know-how to start with :( ).
Well, the 8bit mode works great though, and I guess using
more than 8bit in 1024x768 on a PicassoII+ would be streatching it far
anyway. It's just a pity I can't run it in 16/24 bit in lower resolutions.

>16 and 24 bit modes are deadly slow on a picassoII, anyway.

Actually 800x600x16 is fine on P2+ even though I have a slow
A3640 CPU-board. Or I'm just a very tolerant person. :-)
Though X isn't very usable in such low resolutions of course... 

I guess getting a CV64-3d is easier... :-)
