The startup crash is caused by the game using the difference between two time
values as a divisor in order to calculate system speed. (I'm guessing it's
using GetTickCount().)

It's possible to fix this crash with a bit of hex editing.
http://info.sonicretro.org/SCHG:Sonic_R_(PC) has instructions for fixing the
retail version. (The fix basically NOPs out the timing code.)

I might take a shot at writing a test case for the color key code this weekend.
