Motor Raid is awesome! Thanks for the suggestion guys.
At this point I basically have all the components to finalize my racing set-up (computer w/ a nice front-end running everything from MAME to Teknoparrot), wheel, shifter, cockpit....just missing monitor stand at this point. Unfortunately they are out of stock...hopefully I can get one soon.
One thing - is it just me, or are some of those earlier Sega games not emulated properly. Power Drift definitely seems to have a lot of graphical glitches, even Outun, Turbo Outrun and Outrunners seem off...
Not a big deal because I like the later racing games more...and model 2 onward seems to be emulated well. Same with the Namco racers like Ridge Racer, Dirt Dash etc.
