Using that Greendev fork of Ryujinx and V10 firmware+keys and its working perfectly fine on my end. The fork is also constantly getting updated. Ryujinx itself was NOT taken down via DMCA so Nintendo has really no legal way to go after forks of it unlike Yuzu where they lost in court/settled out of court. Nintendo went and "bribed" the Main Ryujinx dev to split and take his stuff with him.
