Krazy Racers (GBA)

Unlock Vic Viper:
In moon road, there's a long platform thats away from the rest of the track, get the speed power-up, find the first long
jump and use the jump (with a timed boost) to land on the long lane. And there you'll find a diamond that gives you the extra character.


Unlock Bear:
In the metal gear solid level, you'll see to pits near the finish line. Between the pits is a blue diamond. Get it and quit out of the game and save.
Now go back to the character select screen and have a look at the empty space right below dracula.
