First of all, for emulator we have the English ROM hack, so we would be able to pull off possible marriage runs for mii's. And we could add an English Version selection instead if NTSC/JAP (especially to point out emu's)
...
Honestly that's all. Hope these could be a thing!
Also, would I be able to help moderate this community? If not I understand
I'm still not sure whether or not to bring back some other categories for this game, so I'd have to think about it for a bit. Putting JAP instead of NTSC is for console region, considering there's no official Nintendo NTSC release of this game, it's not really a language thing. I also made separate entries for physical DS cart runs and emulator runs to make it more fair (same with 3DS and Emulator Runs for Tomodachi Life).
If you're going to try and route a marriage run, understand that I think pretty much all runs should start with the creation of an island, so try to work that in.
