This is hard to answer. Xmame works and plays games. 8-bit era games generally run fullspeed, later games do not. Some are only playable with bluetooth keyboard. You may need to make custom control mappings for certain games.

The n800 isn't primarily designed for gaming, so there are limitations to take into account. However the games and emulators are a nice add-on function to pass some time. The amount, quality and speed of emulators is increasing over time.

Also, use the forum search feature.
