I know it's not the "official" game, but I've been playing some Ocarina of Time (1998) multi-world randomizers every now and then over the last couple years.
So it is a program running in the program from Archipelago that can connect multiple randomizers together. You can have a friend playing a different randomizer somewhere else and you can send them item for their game and vise versa. Or you can run an a-synch on your own by doing everything you can in one game, and then swapping to another.
They have a list of compatible randos on their website, and I'd be willing to answer any other questions you have
That doesn't even make sense, and I don't know how I feel about. I appreciate the link, hopefully I will get a chance to check it out. Internet is real spotty here
