Bio Hazard for NES is a demake that follows the script of the original Resident Evil game for Playstation.

This game impresses because of the small details. The beginning of the game brings the introduction of Resident Evil 1, originally a video, adapted to sprites. On the title screen, it's possible to start a new game and load a save game from four available slots for saving.

Similar to most Waixing games, the sounds of the game can get annoying and doesn't have any tracks from the Resident Evil series. The menu can be accessed by pressing Start and it is perfectly functional. After obtaining the map, a "map" button will become available on the menu.

To save the game, you need to grab the ink ribbon and go to the typewriter. The battle system and sprites seem to be derived from the Resident Evil Gaiden for the Game Boy Color.
