I've compiled gngeo 0.8 from http://code.google.com/p/gngeo/downloads/list
The emulator is working really fine, i'm able to play Metal Slug, KOF with about 50-60FPS.
I've also made possible to play with the PS3 gamepad via USB and works fine.
The only problem is that I can't use the function keys F1 to F12, someone have the same problem?
Someone have some idea about what can be happening.
The FN keys seems work, if i press CTRL+ALT+FN i go to other tty.
Please let me know if you need more info.
