"Computer Game (Theme From the Circus)" here is actually "Firecracker".
On the album "Yellow Magic Orchestra" "Firecracker" is preceded by a short "space invaders game" soundtrack called "Computer Game (Theme From the Circus)" which is not on this release even though that is its title!
The UK issue of the 12" has the track "Computer Game (Theme From the Invaders)" preceding "Firecracker" (which is credited on that release), which also appears on the "Yellow Magic Orchestra" LP at the end of side A - it is a somewhat shorter version of the space invaders video game!
