Huh, just realized Yuzu was GPLv3. That’s weird. Citra was GPLv2 and Yuzu is a Citra fork. Some of the Citra devs were Yuzu developers, but not all of them, so I wonder how they handled the relicensing. Yuzu had a CLA attributing copyright to the creators, so that wouldn’t have been a problem, but Citra had not such thing.
