Some later
Game Boy and
Game Boy Colour cartridges contained
rumble-packs (such as Top Gear Racing), designed to enhance reali... check that, they were just a stupid battery draining
gimmick. To return to the point, don't ever, ever think about putting one of these into a Super Game Boy. Your
SNES will make hilarious clacking noises for a few minutes as it shakes around the desk like a
mobile-phone on vibrate, then cease to function forever.
The SGB was also emulated within the
Pokemon Stadium games on the
Nintendo 64, although with additional options to increase the
emulation speed up to four times real-time.
Lastly, some early previews of the
Nintendo Gamecube were running some form of "Super" Gameboy Advance emulation - reports from
E3 had
Gameboy Advance plugged into the controller ports of the Gamecube, with the GBA graphics displayed on television screens. This technology now seems to have materialised in the Nintendo
Gamecube Game Boy Player - this fits in one of the expansion ports on the underside of your Cube, and lets you play Game Boy, Game Boy Colour and Game Boy Advance titles on your TV screen. If you have the
Gamecube GBA Cable, you can plug in 1-4 GBAs and use them to control the games, and even play link-games (possibly split screen?).
