Not only did their developers harrass Near (developer of bsnes and higan) to s*icide, they also harrassed stenzek (developer of DuckStation) to the point he has abandoned the project.
There are also several other emulation developers who claim to have been harrassed by RetroArcheholes.
Just look at this shitshow. Use standalone emulators! Take back from the money-hungry harrassers!
