Years ago, after Xbox Live for the original Xbox shut down, there was a program you could run on your PC that would connect over the internet to others running that software.
It would emulate an Xbox and do matchmaking and your local/physical Xbox would see the others through the program 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.
Some friends from college and I dug out our old Xboxes, and we want to setup remote play for Halo 2 and have a nostalgic “Shotguns on Midship” night.
Update: Solved. Thanks, [email protected]. XLink Kai was the software I was thinking of.
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!
