Sega Master System: Japan version BIOS demo [4K]

This is 4K RGB capture of what you get when you boot up a Japanese Sega Master System without a game inserted: Namely, an 8-bit FM rendition of the Space Harrier theme with some dancing stars as you skin an infinite checkerboard. No snails for Japan... only jams. This BIOS demo is only present in the Japanese Master System, not the U.S. or European consoles, and not the Japanese Mark III. Recorded from a Japanese Master System via RGB, upscaled to 4K via RetroTink 4K. Feel free to use for your own purposes, I guess?
