Jetsons, meet the Jetsons, they're a modern space-age fa-mi-lyyyyyy...

Level Select

In the US and European versions, Game Genie code VOOOGONU enables a level select mode. The screen is pretty self-explanatory, but don't select CHRSET as it'll just lock up the game.

(Technical explanation: the code jumps to $6000, which is the beginning of SRAM/WRAM. However, this cart has none, and the game never attempts to write to it. A ROM chip or other device most likely occupied this space during development.)
