GBC isn't very likely. It has quite a few more hardware features I would have to implement, not to mention twice the RAM and processor speed.
And linking could be possible... I haven't really tried it at all yet though.

Hi, I also found this forum because of the emulator.
anyway,
SOME .gbc roms should work without a problem, like pokémon silver/gold since it works on the original game boy.
Also, I haven't tried the emulator yet (need some new batteries) but my serial number ends with S-0507 H.
This means it's ONE revision too young?   It's over two years old.
