I've been thinking about this for a while, but coming across this old article from Nintendo World Report, it convinced me to ask online about it. I'll put the link here for reference:

Basically, for any sort of homebrew development, what can one theoretically do with the Game Boy Player and the GameCube hardware, beyond simply displaying games that are running and accepting input from controllers? I know that GBI can dump a rom to a connected SD card, but I would think a lot more should be possible. I'll list off some idea, some inspired by the article above, others just of my own invention.

- Running the GBP at the same time as a standard game, and possibly overlaying the output of the GBP over part of the TV.
- Run a GCN game, but use the GBP in tandem with Link Cable or Wireless Adapter to have more players on the same console, having interactions similar to the Wii U and its Gamepad. Theoretically, four controllers and four GBAs could be connected for larger scale asymmetric gaming.
- Have a GBA game that can save content to the Memory Card--stuff like saves, levels, extra content--and then access them in gameplay.
- Allow a GBA game to have internet connectivity through the BBA. LAN connectivity could also be an option.
