I love The Simpsons arcade cabinet, and I don't know anyone who doesn't. So I know exactly what you mean when describing the hypnotic powers it has on gamers who wander in the machine's vicinity.
Playing The Simpsons on Mame, however, was a bit of a letdown, as the price of a continue was equal the distance of your finger to your keyboard's "insert coin" button. As playing on an emulator made you infinitely rich but was no fun, perhaps this is why people say money does not equal happiness?
But of course I'm way off subject. Simpsons would look beautiful on the GP32, just as Day of the Tentacle and other similar pixelated 2d games do, by realizing a sharper graphical appearance useful for when you want to immerse yourself in the game and not study the art as you might on a larger screen.
