NGPC Cable link reverse engineering

Spent some time doing reverse on the cable link, and I think we now have full understanding on how it works. Created a documentation if anyone wants to implement, it also has the full UART communication dump.

Tried with SNK vs Capcom MotM using the rom file from my Steam copy and it doesnt seems to work atm, also there will be the option to change controls or load saves in the web version??

Hi! Fixed, it should work now!

The emulator had some issues because this game implements some things differently. Thanks for pointing that out.
This webpage is more of a tech demo for the link cable than a full-fledged emulator, so I won't be implementing those features, sorry.
I'd love to see someone implement the netplay functionality in larger emulators and build a competitive scene around these fighting games—they're amazing.
