I've played/still playing a couple of PS1 games like Final Fantasy 7, Final Fantasy Tactics, Tekken 2, Ridge Racer, Grand Turismo, etc on an RPi3B with RetroPie/Emulator Station.
The emulator even has provision for saving to a "memory card slot". Quite handy for RPG games like FF7.
Plays quite well, cant see any difference from the original PS1.
"Don't come to me with 'issues' for I don't know how to deal with those
Come to me with 'problems' and I'll help you find solutions"
Some people be like:
"Help me! Am drowning! But dont you dare touch me nor come near me!"
