81 red did come up with a fix for the gear problem in MR1, but it looks like motoracer 2 is out of luck at this point:
81RED: I have found an alternative .EXE that enables the missing gears and seems to be functional in all other respects as well.
Moto Racer 2 is an entirely different beast - the GOG.com EXE is byte-for-byte identical with the 1.36 version cracked by scene group MYTH, and happens to be the only version locatable anywhere...which could mean that we are shit out of luck...
While, I am completely in favor of finding a fix rather than complaining and asking for my money back, like songblev said, if this is not fixed soon, I will be asking for my money back. As is the game is broken and unbeatable.
