GSzzogl fails under virtualbox
#1
I've tried to run pcsx2 under virtualbox (4.0.10) with ubuntu maverick.
Installed version 1:0.9.8.0-0ubuntu1 from Gregory Hainaut ppa.

At reboot pcsx2 draws empty screen in zzogl output window.

I would appreciate if anyone can explain what do errors in zzogl log mean,
and what can i do to run the game.

Use ATI_texture_float for blockdata.
Fill bilinear blocks OK.!

P.S.
Actually it is not black screen, but black hole (random stuff like another parts of screen displayed there)

The game runs quite well on real hardware (GeForce GT 220 with driver nvidia-270.41.06),
but sometimes it deep hangs X11 screen and input w/out ability to easy recovery.

I suspect that vbox does not support all OPENGL extensions needed by zzogl.

Is there any way to figure out what extensions needed for zzogl?

I do not know, but a good target will be opengl 3.0 support.
