Splatterhouse/Versions

Home versions of Splatterhouse were released on the TurboGrafx-16, FM Towns and PC. In addition to loss of graphical detail and removal of some sounds (standard for a port to less powerful hardware), the following edits were made to both the Japanese PC-Engine and North American TurboGrafx-16 versions of the game:
 * The arcade version opens with an animation of Rick and Jennifer running through the storm and into the mansion, followed by an exterior shot of the mansion and the sound of Jennifer screaming. The console version opens simply with the exterior of the mansion, and no sound effects.
 * The weapon in Stage 1 and Stage 2 is changed from a meat cleaver to a wooden stick.
 * The overall violence and gore is toned down; enemies bleed less and the sound effects are less gruesome.
 * The weapon for the Stage 4 boss is changed from an ax to a golden meat cleaver, the only cleaver in the game.
 * The crawling hand in Stage 5 no longer flashes the middle finger.
 * The death of the womb boss of Stage 6 is changed from a graphic spilling of embryonic fluids into a generic fiery explosion.
 * The final boss uses different attacks.
 * The end cut scene is changed from the original arcade ending, in which the mask breaks from Rick's face, followed by a shot of him walking away from the burning mansion and an additional cut scene showing the mask reform and laugh. The ending in the TurboGrafx-16 version only shows the mask explode, followed by a picture of West Mansion burning while the credits roll, and finally a large red and orange "End" is displayed.

The following edits are exclusive to the North American TurboGrafx-16 version:
 * The Terror Mask is changed from a white hockey mask to a red mask with black accents. This is to keep Rick from looking too much like Jason Voorhees. The mask became more skull-like in later games.
 * The cathedral arches are removed from the Stage 4 boss chamber background and the altar is removed from the following cut scene.
 * The inverted cross boss of Stage 4 is replaced with a severed head.
 * The final boss' grave is changed from a wooden cross to a tombstone.

The TG-16 version was released on the Wii's Virtual Console in Europe on March 16, 2007; in North America on March 19, 2007; in Japan on July 3, 2007; and in Australia on July 20, 2007. The arcade version was released on May 26, 2009 on the Japanese Virtual Console.

The FM Towns version, ported by Ving Co. and released only in Japan in 1992, is a pixel-perfect rendition of the original arcade, with no substantial changes apart from a new menu interface in the title screen. A few sound effects were changed or even removed, such as the intro theme to Stage 4 being cut and the thunder in Stage 3 sounding heavier compared to the original. There was also an LCD handheld version released, titled Splatter House, but it is not a port of either games. It is considered to be an original Splatterhouse game in and of itself, though many elements in it are similar to the original game.

In 2010, the game was ported to J2ME/BREW mobile phones, Windows Mobile and iOS platforms to coincide with the release of the remake. The only change was in the Java-based mobile phone version, where Rick's mask is modeled after the skull-like one present in the remake. This change is not present in iOS version of the game, but it includes a "Splatter Rush" mode instead, where enemies continuously spawn from both ends of a wide screen. The remake also included the uncensored Japanese arcade version as an unlockable extra.

It was also included as a part of the Namco Museum compilation for the Nintendo Switch, through the Nintendo eShop. The title is also playable on the Turbografx-16/PC Engine Mini.
