Metro-Cross
is a platform arcade game that was released by Namco in 1985. It runs upon Namco Pac-Land hardware (but with a video system like that used in Dragon Buster, modified to support a 2048-color palette). It uses a Motorola M6809 microprocessor, with a Hitachi HD63701 sub-microprocessor (both running at 1.536 MHz) and Namco 8-channel waveform PSG for audio.
