Star Force [Japan] - NES - longplay
9The North American and European versions for the NES were published two years later, in 1987, with significant revisions, and with Tecmo credited rather than Hudson on the title screen and box art. According to Keiji Yamagishi, the NES version was created separately at Tecmo and is distinct from the port released for the Famicom by Hudson.
Although the NES version is immediately recognizable as having a great deal in common with the Hudson version released in Japan, there are significant alterations to the graphics, music, and controls and gameplay. Several bugs in gameplay were fixed (debatably making the NES version more difficult) that allow the player (in the Japanese version) to prevent new enemies from appearing ("spawning") by not shooting the enemies already on screen.
Another great difference is that japanese version is actually endless, with infinity zone looping literally infinite times.
Western release shows a brief ending after the Omega stage, then the Infinity level wil start, which repeats infinitely: • Star Force - NES - ending
