I took the Super Game Boy code I made for Petal Crash GBC and made a code example that shows off booting custom SNES code and then having the Game Boy side send files to the SNES as needed.

The text at the top is the result of asking the Game Boy to calculate $AA + $BB and send the answer to the SNES, as an example of doing other tasks than just getting files.
