As someone in Europe,
So here’s what to expect if you manage to change your region. I have no idea on how to do that however.
Besides Funkwhale, I’m not sure there is anything else at the moment (someone please correct me if I’m wrong)
There are radios on Funkwhale, but these are just a random playlist of songs from a set list (like “Piano radio” for example)
Peertube has a livestreaming function that could be used as a radio closer to the actual sense of the word (with someone animating it), but it would take a lot of effort and I haven’t found any radio channels on Peertube. If you have a great idea, go for it and it might take off! 🎉
You should check out this fork by the person who made CTGP7, there are portable releases
Here’s a fork of Citra that can connect to the official nintendo network, still avilable now, by the person who made CTGP7 (custom tracks and characters in MarioKart 7), and here’s the one for Yuzu. I think these are gonna be the main forks because they already have quite a lot of activity. It’s cool that Citra and Yuzu were open-source so things like this can be made!
