@fernaretro yes, please do.
I have 44 systems running well over 3500 games across them... all on a Pi3b+ standard settings, no overclocking. I get pretty good results until the Amiga 1200/IBM PC/Atari St/Apple IIgs era of games. Then it's a little touch-and-go with the performance. I don't run any N64 and very few PS1 games. No PSP games at all.
I'm thinking it's time to move up to a Pi4, but I'm waiting till the next revision. From what I've read, it will be returning back to a standard HDMI slot which is what I want.
