Gray screen problem and a possible solution.

[hyakki]

nothing in jpcsp uses net framework...

anyways quickest way i can think of to find video card is go to device manager -> Display adapters

to find opengl version edit LogSettings.xml in jpcsp main directory find where it says
<root>
<level value ='off' />

change 'off' to 'Info' save, then start jpcsp you should see the opengl info in the logger window or in Log.html

you might just need to update your video card drivers, it could be using generic windows driver or even vga drivers if you never installed any. Jpcsp works on my other pc's really old geforce 4 video card, so I highly doubt you have something older then that (if its older then that then i'd consider a whole pc upgrade).
