This is a neat find, but it's unfortunate that a RCE/ACE like this is so limited by the Game Boy Color itself. Most of the interesting electronics are in the cartridge, which can already be replaced by something that runs arbitrary code anyways.<p>It would be neat if this could be used to exploit an emulator or an adapter (e.g. GBA link for GameCube) and get ACE on something more powerful/inaccessible.<p>Congrats on the WR, though.
