Some trouble with gaming

[brbtrg]

Hello,

I have some trouble with running games:

1. DOSbox won't save my mounted directory. After closing every setting is gone.
2. If I run a game on DOSbox (like Stunts and Mario), the keyboard doesn't work (only the escape-key works).
3. I have trouble with 3D games. Vdrift has no sounds, races in Torcs and Ultimate Stunts won't start, and Trigger, Urban Terror and some other 3D games won't run at all.

Can somebody help me? Thank you in advance.
