@maple That's true, I suppose most early consoles actually do have a little RF port in addition to whatever they're doing for composite.
@NovaSquirrel @maple Oh wait I forgot that my SMS had a DIN port on the back that didn't come with a cable and I never understood the function of... and then SNES ad the AV multi out... never mind ha ha.
@NovaSquirrel @maple There were other consoles besides NES that had both RF and composite outputs?
(Once you get to HDMI + Composite consoles all the ones I've seen are one-at-a-time, PS3, Wii U, etc.)
