I compare the first three levels of the SNES version to the Factor 5 ported Gameboy version, a port that's missing some levels and a few bosses. Despite that, it's still pretty good.
I switch to SNES footage only when there's a boss that's not present in the Gameboy version or when a section of a level is longer on SNES. I also swap the sound back and forth between both versions throughout the video.
The SNES version was recorded on real SNES hardware via S-Video, and the Gameboy version was filmed using the Gamecube's Gameboy Player via S-video.
