Adding connectivity could lead to integration with RetroAchievements and online 2-4 multiplayer. Imagine Contra with a friend online. Or save states with cloud saves. Leaderboards! It could actually become connected to online NES communities and existing web services to ensure it stays alive. That would be so cool

Imagine a game genie like cart for snes that gave kaillera multi-player capabilities to games, along with an eth or wifi card connected to this port.

  There’s a game for NES trying to do this, kinda. It’s called Super Tilt Bro and has a chip to do WiFi multiplayer. Obviously not the same scope, but cool idea on real hardware

A 3rd party modem for SNES and Genesis existed, and used the cartridge port: XBⱯND launched in late 1994 and sunset in 1997.

You can actually do online multiplayer with retro NES/SNES games now using Nintendo switch online. There have also been several NES emulators that support online play.

  Which is great! However with this expansion, the original hardware would be able to do this too.

This already exists on the SNES with the usb2snes/SNI family of protocols. On original hardware, it requires a flashcart that can sniff the memory bus and interface with a host PC over USB. Some things you can do with this include: - RetroAchievements, as you mentioned - Automatic timers/splitters for speedrunning - Co-op mode for Super Metroid: https://m.youtube.com/watch?v=ilG70fc-IJA https://m.youtube.com/watch?v=ilG70fc-IJA - Multiworld co-op randomizers for games like Super Metroid or A Link to the Past -- two or more people play linked randomizer seeds over the Internet, and the items are distributed across games so you can find items for other players in your game: https://archipelago.gg/ https://archipelago.gg/
