"Q: Is it compatible with the Super Game Boy? The 32X? The Power Base Converter? The Master System Converter II? The MegaMaster? [...]
A: Until further notice, not in a useful way. What you might get is some ROM portion of the extension device itself, such as the Game Boy border of the SGB. For anything more, the chances are ridiculously low (the number also known as “zero”), really.
Update: Actually, using the 32X adapters the Retrode has been found to read 32X carts, so woo-hoo there."
So to clarify, the "update" just says that the 32x will work, whereas the Super Game Boy continues to not work?
In that case, I guess I'll just wait patiently for the gameboy adapter/attempt to build my own...
