Two developers on by the names of TheDrifter and Xiota have done a very good job on separating and re-branding the Primehacks internal structure on Linux from Dolphin to make them not be in conflict.
TheDrifter maintained his own fork before soon merging it into Primehack proper with these changes for a long time. RetroDECK always used this fork because it would otherwise conflict with Dolphin (as we ship both inside one application).
Us in the RetroDECK Team have always communicated with them and supported them on in their efforts and we are happy that the changes are hopefully soon in mainline Primehack.
