Hacking Is data communication possible through the gamecard slot?

[kalashala]

is there a reason why for over 13 years nobody has made a custom pcb to use the 8 bidrectional buses on the gamecard slot for communication? it could be used for video capture and so much more.

ive been planning on doing something exactly like this for a bit so before i embark on my journey i want to make sure that its actually possible.

Sure. Checkpoint and such can access the card slot so I don't see why not.
