Personally I first started with an emulator called VBA advance due to wanting to play the fan translated verison of SRW J. Then I started playing gba/GB series of games then moved to the nes then snes then genesis then the arcade starting with Winkawaks then mame then the flipping playstation with epexe the bios took a while to get used to then the dreamcast. All of this from the early 2010s.
