How did Tropic Haze make money if Yuzu and Citra were free. I could not find other products they sell. In consequence, how could they pay millions to Nintendo?
They had a Patreon that pulled in tens of thousands per month. If I recall correctly, some features were locked to early access that required being a Patreon member. https://graphtreon.com/creator/yuzuteam
This situation really sucks because soon there will be the Switch 2, and then maybe in 5 years or so you won't be able to play a lot of these games easily anymore (nevermind at good resolutions, etc.).
