Strider Hiryuu (1994)

NEC Avenue's Strider Hiryuu is a port of the coin-op for the PC Engine. This port is infamous for its protracted development, as it was originally announced as a HuCard for the PC Engine SuperGrafx in 1990 before undergoing various format changes, ultimately being released as a CD-ROM game for the Arcade Card add-on in late 1994. Its most noticeable changes are new animated cutscenes, arranged Red Book-quality soundtrack, and an optional bonus mission between the first and second stages, set in a desert. Otherwise, the game plays similar to the coin-op. The new cutscenes appear to have inspired the later Strider 2, as both games use similar wireframe maps for their stage introductions.
