My college roommate had this little box that had 2 controllers and RCA’d into the TV that contained basically every game from the most important retro consoles. All the important consoles and games pre y2k. Including Nintendo, Atari, Sega, and maybe some arcade. I assume I can’t get it through normal channels because of some of those roms are unsanctioned, but where might I get something like that? Thanks!
Looks like someone is ready to start enjoying retro gaming! For real beginners I recommend Data frog SF2000, for about €15 you get device that can run 6k games (and it arrives with RCA cable too) and doesn’t require poking Retro arch settings. Once hooked you can search and find dedicated device that can run more advanced consoles, can be plugged directly into HDMI port of your TV, etc.
