were later replaced, by Rebecca and Barry, respectively. Almost all development was done on Silicon Graphics hardware using the software program Softimage. The PlayStation was chosen as the lead platform because the development team felt it was the most appropriate for the game in terms of things such as the amount of polygons. The development team had upwards of 80 people towards the end of the game's development. According to Akio Sakai, head of Capcom's consumer software division, Capcom were hesitant to port Resident Evil to the Saturn because the hardware was not as ideally suited to the game as the PlayStation, ensuring the port would take a long time. A Saturn version was finally unveiled at the April 1997 Tokyo Game Show, at which Capcom also showed a demo for the sequel on PlayStation. The live action full-motion video sequences were filmed in Japan with a cast of American actors. All Japanese releases contain English voice acting with Japanese captions and text. However, Japanese voice performances were also recorded but were left unused, as Mikami found the quality of the performances inadequate.

The original Japanese PlayStation version also features a vocal ending theme, , performed by Japanese rock artist Fumitaka Fuchigami, that is not in any other versions of the game. Fujiwara said the game was originally targeted towards a core audience and he only expected it to sell around 200,000 copies, before the game went on to sell millions. Mikami said he was "a little worried about how well a horror game would really sell." Anpo said that Capcom did not expect the game to be successful.

Among others, the 1992 video game Bio-Hazard Battle and the New York alternative metal band Biohazard were already using the name. Capcom therefore ran an internal company contest to find a new name. The name Resident Evil was settled upon since the game takes
