After learning about the existence of the Pokemon Yellow homebrew I had a thought... would it be possible to make a "link cable" that plugged into two famicoms extension ports that would serve the same function as a gameboy link cable? Obvious Chinese Yellow doesn't support it, but hypothetically if someone were to make another pokemon Famicom game from scratch would that be possible to do?
(Alternatively I guess if someone made a homebrew game for the famicom disk system trading could work by selection a pokemon from a menu to be traded and loading that data into the ram, inserting another copy of the game, selecting a pokemon that would replace the RAM data and then putting the original game back in)
Anything is possible. The matter is motivation and time.
But the famicom extension port is capable of transmitting game data?
Do you have Family Basic keyboard?
No, but I see your point.
I found this thread while post-digging. I'm interested in this kind of stuff. Maybe someday someone on the forums could start a FC Pokémon and Data Link Cable project. Unfortunately, I can't ATM.
This is a mammoth task, I wouldn't hold you r breath squire.
