So... I was thinking back to the days of le NES and SNES.
I would love, to hack an old NES controller,
put an ssd or big enough USB drive inside it. (filled with the emulator and all the NES roms I could want)
Run the USB Cable as the cord.
And Voila, legit old school gaming feel brought to new school.
Lather, rinse repeat with all other gaming systems you feel necess.
