Lots of versions released, with differences in stages, physics, hardware.
Kinda hard to nominate a best one, but tyhe important thing is that they all rule.
Mod that adds force feedback support, and some other nice touch-ups / updates.
There's a folder called 'Savegame' in the 'OutRun…' directory, with the files 'License1.dat' and 'common.dat'.
When I had it installed in 'Program Files' those .dat files were not actually created though. But saves still worked! I assume a permissions issue, with a built-in workaround? Not sure where/how that works. Can't find anything in AppData, or My Documents, or anywhere obvious
When uninstalling it will ask if you wish to keep 'licence data' :)
