It's obviously a clone of Atari's Championship Sprint (minus the upgradeable cars feature) and, while I won't comment on its quality, it's nice to have it preserved.
The hardware is fantland.c with a NEC V20 as main CPU, and a Z80 as sound cpu (in place of the usual 8088).
It is almost fully working, but I had to resort to a few hacks in the video emulation, that I'll have to investigate further and implement properly.
Plus, it's obviously trying to play the crash / hit sounds by driving two I/O ports, but not like DAC's. Indeed, some other games on this platform use a custom sample player in place of the DAC's, but in this case there are no sample roms. So that will require some more work.
