RetroArch recently redid its UI from the ground up. It’s 1000% better now. It’s so good I’m going to be pushing it as my top recommendation for 8-bit/16-bit/32-bit gaming systems.
One interesting feature of RetroArch’s PlayStation 1 emulation: it can fix the jittery of 3D animation. The animated GIF above compares both modes -

However, Saturn emulation is still poop on RetroArch. uoYabauseis still my top recommendation for Saturn emulation, and SSFsecond.
