- Keep Circulating the Tapes: Similarly to SegaSonic the Hedgehog, the game relies on the cart's motion sensors to be played and has never been rereleased (not even on the Nintendo 3DS, which has a built-in gyroscope). If you're going the emulation route, specific emulators are needed to run it, and even then the controls will be oversensitive if you don't have a way to properly emulate the tilt controls. If you have real hardware, not even the most advanced Game Boy Color flash carts can replicate the game's motion sensors as of 2021. As a result, while not too rare, the game can still fetch a pretty penny on secondhand gaming markets simply because that's the only way to really play it, and even a loose cartridge can cost you.
