That reminds me, I've read that the SGB only adds 10 or so colors to the actual game display IF it has been designed to be used with it. Despite coming out later, I assume it wouldn't be possible to make the DX games display the same way through the SGB as it does on a GBC, correct? The GBC uses 56 colors total, while the SNES is around 256, so it should be somewhat logical; you might need to reprogram the game for that, though.
How advanced is GB and SNES dev, anyway? And SGB development, for that matter?
