I just configured a Raspberry Pi 3 running RetroPie 4 on top of Raspbian OS so I can play all my old school ROMs on my 50" TV with ease.
It's one of the coolest and most fun nerdy things I've done in a while. I have essentially the entire library of games for NES, SNES, Sega Genesis (MegaDrive) and N64. Working on overclocking to run PS1 games and trying to figure out how to get MAME (Multiple Arcade Machine Emulator) ROMs to work.
I figured I'd start this thread so people can discuss retro gaming using ROMs on PC or share ideas about getting the most out a RetroPie/Raspberry Pi set up.
