Just that Suyu isn't doing anything illegal or against the law. Emulation is legal. Also reverse engineering if it's done right in a lot of countries. What discord did here wasn't because of the law but because they are feared of Nintendo being mad at them.
Ryujinx don't works on android. So also not on the Odin 2 Pro as an example. that's why (for me).
did you try annas-archive? maybe you find your books there. i always did buy from amazon and then removed the drm and stored it offline on my pc so amazon can't take them away.
why? because it feels safer to join a big and longer lasting instance than a random one with almost no users. such small instances can vanish from one day to the bext. i once created a account on such a small instance and not even a week later it was wiped from earth, taking my account with it. so it's no wonder people chooser rather bigger instances.
"sue-you". Suyu. it's a clever wordplay. i love it.
i heard that's already in development, so it probably will come sooner or later
