Image Fight & X-Multiply is the Playstation conversion of 2 Arcade Machines.

A compilation of two classic Irem shooters, Image Fight and X-Multiply. Both are based on the superior arcade versions (Image Fight was ported to the NES.) Image Fight is a top-down blaster through the blackness of space, while X-Multiply is very similar in design to Irem's most known shooter, R-Type (it even features add-on components similar to the option subship.)

Kouryuu Sangoku Engi (??????) is an historical simulation game for the Sega Saturn.

Gun Frontier is the prequel to Metal Black, another largely unknown shooter, this time a Darius-like horizontal blaster, which was also released on Saturn by another company called Ving - nothing to do with the publishers of this game though. Gun Frontier was ported to the Sega Saturn in 1997 (as volume 2 of the Arcade Gears series)
