Hudson Soft developed a fairly accurate port of R-Type that was released for the TurboGrafx-16 (a.k.a. PC Engine) console, although it suffered from a slightly lower resolution, reduced colour palette, sprite flickering and slowdown. Due to the slightly reduced resolution, the playfield also scrolls slightly in the vertical axis whenever the player's ship approaches the top or bottom of the screen. The Japanese release was split across two game cards (HuCards) titled and and the later North American release contained the entire game on a single card. The TurboGrafx-16 version of "R-Type" has a boss at the end of Stage 6, rather than a prolonged wave of enemies as in all other versions.
