On Jimmy Neutron, Sheen has a game system that is the best reinterpretation of a GBA ever! Also, on the same show and on the camping episode, when Jimmy sets up camp, there's a video game system. Not just any though! It's the best reinterpretation of a NES ever! The squarish one that's more widely recognized. Timmy on TFO has a GBC. Um, that's all I can think of. So far...
Forgot one! In a Mucha Lucha episode, Ricochet gets edicted to an online computer game. But, the game has various Mario sounds, like the 1up mushroom and the coin sound.
