So I grabbed the X-Arcade trackball today, thinking that if nothing else, it will tide me over until I get my new ipac, and suprisingly, I really really like it. But I could use some help from the experts out there who've been trackballing it for awhile... there are a LOT of adjustments in MAME for trackball settings, and while most of the games I've played (Millipede, Star Wars, Missile Command) work great, Marble Madness is really sluggish... can someone walk me through what the settings do and maybe hook me up with some specific settings to try out?
Also, other than the old Atari standbys, any trackball game suggestions?
