So basically the idea is for a mod to replace the link cable with wifi arduino board. And use that to emulate a physical cable. Maybe have a tactile switch for pairing. Any ideas or suggestions on where to get started would be helpful.

Sorry, but your idea got stolen 20 years ago.

I aware of the bulky wireless transmitter. I would like something smaller that would fit inside of a gba shell.

Why would an Arduino be small enough to fit in the shell?

Maybe... an antenna or something closer to Bluetooth module. But an Arduino, as far as I know has roughly the same size as a GBA mobo.
 
The Espo1 is a smaller wifi module. I was thinking something along those lines. Can't post a link bc I'm a newbie

Basically the issue I'm running into is Documentation on how the link cable port works. Not to savvy when it comes to programming. But good with hardware mods. So I'm curious if anyone has knowledge of how the Espo1 wifi module works and if it could emulate a link cables function.
 
for reference they made this at one pointacts as a link cable and works on most games but not pokemon funnily enough

honestly after looking at the Pico w im thinking it's a better pick due to both wifi and Bluetooth support

The original Pi Pico also got many smaller, more compact versions of the board made, I'm curious if the W got the same treatment (or will) to save on internal mounting space.

After watching the video I may buy one to disassemble. It at least is a good starting point thanks
 
I think this might be useful.
The guy made a successful custom pcb to trade Gen 3 Pokemon back to Gen 2.
So, he must have documentation somewhere:

Sorry to burst your bubble but the reason why no one did this yet is because link cable communication requires extremely low latency. Not even USB is fast enough. The best you can really do is emulate the wireless adapter. However i don't think you can get much smaller than the original wireless adapter. That being said it may work with certain games as GBARunner2 proved but the majority of games don't work correctly or have frequent connection issues.

The problem is that wireless adds some unavoidable latency and games expect pretty much instant responses. If you want to connect to other GBAs over the internet not even the wireless adapter may work due to the high latency.

Sounds like the GBA needs to learn some MF patience. :evil:
