Makes sense, but which version is the one I'd want to search for?

Compare Street Fighter II console versions for SNES and Genesis, noting character count, gameplay pace, and sound differences.

The earliest console ports of Street Fighter II were released for the SNES and SEGA Genesis. These versions are scaled-down adaptations of the original arcade game to fit the hardware limitations of these systems.

The SNES version notably removed the original title screen, while the Genesis port retained it. Both versions feature only 8 playable characters, a slower battle pace, and lack extra game modes beyond Arcade or Versus. The character select portrait artwork is described as sloppy, and most characters are missing certain special moves. The music in these ports is characterized as terrible MIDI tunes, and only three voice actors were used: one for the announcer, one for the sole female fighter, and one for all the male characters. This limited sound variety makes these early ports feel dated.
