If you have a different version, exhibiting the same issues, it should fairly easy to find the place where to patch the executable.

In general: That game will most likely only run in Win9X compat mode on Windows NT systems. I wonder how/if they did a full Intel 8253 emulation to allow this code to work or if they just cheat with an application shim, having GetSystemInfo() _not_ returning i386/i486/i585 to avoid the critical code path.

You did an awesome work there, the game then runs with wine. However the game is still unplayable as cars go slow, they seem to brake, including our car. Other cars do the same, making the game quite easy. On the first mission Taurus car goes very very slowly and often brakes, same for ennemies. On the second mission our car and Taurus car go too slow and can't pass the "jump". I think it's framerate related or something, there is another piece of code in the game that seem to log and calculate framerate, it's probably buggy. Somehow the sky passes VERY quickly, but cars go too slow. Same issue on recent windows with recent hardware, it was working on old windows+old hardware only.

In general: That game will most likely only run in Win9X compat mode on Windows NT systems.
and it also works on wine for me when setting the windows version to win98. the privileged instructions get correctly emulated. see __wine_emulate_instruction in dlls/krnl386.exe16/instr.c it would argue there is nothing to fix here. Wine matches the windows behaviour. (In reply to Kevin from comment #7)
