I can’t say anything about the whole license drama because I’m not involved in the subject at all, but I don’t think it diminishes a community-driven project that one of its developers made mean comments in the past. And I can’t help but find some of these posts on Reddit and Twitter very amusing - the ones where people announce that they will boycott RetroArch or ask people not to use it anymore. It’s literally a free, open-source program, nobody cares whether you boycott it or not! You can even use RetroArch and donate money to the developers of the original emulators, who is keeping you from doing it? Are people feeling dirty because they installed it on their PC or something? This mentality is absolutely baffling to me, and so are the people who now claim that RetroArch never had a use in the first place and that standalone emulators are much more convenient anyway - yeah, sure. That’s like having a different audio player with a completely different user interface installed for every band that you’re listening to.
Plus I’m super grateful that RetroArch keeps projects like Genesis Plus GX alive and makes them available on platforms where they originally weren’t.
