Bugs Bunny in Double Trouble (Genesis)

Cheat Menu
At the main menu, press Down, Down, Left, Up, A, C, Down, Down, then press A+B+C+Start.

The functions are as follows:


 * Start Map: Level Select.
 * Cheatmode: 0 = None, 1 = Invincibility, 2 = CPU usage meter (?)
 * Play Sound: Sound effect test
 * Play Tune: Presumably a music test, though it doesn't seem to work. There's a functional one in the regular options menu, anyway.
 * Joyrec: No idea what this one is supposed to do, and none of the controller buttons seem to change anything...
