Doom 64

The Japanese version of Doom 64 for the Nintendo 64 was released on August 1, 1997, published by GameBank. While the gameplay is identical to the North American release, there are several unique regional differences:
Green Blood: To comply with Japanese censorship standards (possibly influenced by the Kobe child murders at the time), blood splatters were changed from red to green. However, some death animations and "gib" objects inconsistently still show red blood.
Higher Default Brightness: The Japanese release has a significantly higher default brightness setting than the notoriously dark US version, making it easier to play on standard television sets without adjustment.
Minimal Translation: Despite the Japanese release, the game is not fully translated. Most in-game text remains in English, with only small pop-up messages for items occasionally localized.
Box and Cartridge Art: The Japanese box uses a portrait orientation (vs. US landscape) and replaces the "Demon Artifact" cover art with a simple dark slate background and a larger logo.
