Years ago, after Xbox live for the original Xbox shut down, there was a program you could run on your PC that would connect to others running that software.
It would emulate a local Xbox and do matchmaking and your local Xbox would see the others as “local” using the system link option for multiplayer games (Halo, etc)
For the life of me I cannot remember what that was called, and my Google-fu is failing and only returning results for console emulators.
XBConnect
That’s similar, but it’s not the one I was thinking of / familiar with. XLink Kai was what I had in mind. However, at this point, I may have to check both projects to see if either of them can still work. Thanks!
XBC was amazing!
May want to look into insignia too, its a xbox live replacement, its still a WIP and doesn’t support some games, including halo 2 unfortunately, but the games it does support work very well
XLink Kai? I remember it from late 2000s, I don’t know much about it now.
I do believe that’s it! Thanks!
Now to see if it’s still active or even works.
I used warpipe for GameCube and I think it also worked for Xbox
