I had decent success with PS1 games on the Pi2, which surprised me. Most games I tried ran well. I haven't tried on the Pi4 but I assume it's really good, based on that. PS2 might even work well, there. N64 was another story, but N64 emulators have improved a bunch since last time I tried. I think the only game I found that played acceptably on the Pi2 was Mario64. Most of the rest were slideshows or didn't run at all.
