In late 2000, Capcom officially halted production on the N64 version and shifted development to Nintendo's next-generation console, the GameCube. The GameCube’s proprietary optical discs offered 1.5GB of storage, allowing Capcom to scrap the low-poly models and build the hyper-realistic, atmospheric masterpiece that was eventually released in late 2002.

Because a fully complete, consumer-ready ROM of the N64 version does not officially exist, the community has taken preservation into its own hands.
With the Nintendo GameCube on the horizon, Capcom made the difficult decision to scrap the N64 version. Production was shifted to the GameCube's high-capacity optical discs, allowing the team to completely overhaul the graphics using the Resident Evil Remake engine. The N64 version, estimated to be roughly 60% to 70% complete, was shelved forever. What the N64 Version Looked Like
In the late 1990s, Capcom announced a shocking partnership with Nintendo. The next mainline Resident Evil game would be exclusive to the N64. This came on the heels of the miraculous Resident Evil 2 N64 port, which squeezed a two-disc PlayStation game onto a 64MB cartridge. Resident Evil 0 N64 Prototype Rom
Analyzing and running the Resident Evil 0 N64 prototype ROM presents unique hurdles for the digital preservation community.
For decades, this unreleased version existed only in grainy magazine scans and brief promotional VHS tapes. Today, the search for a playable Resident Evil 0 N64 prototype ROM remains one of the most compelling preservation hunts in survival horror history. The Origin: Why Resident Evil 0 Started on N64
Yet, the atmosphere is unmistakably Resident Evil . The train’s dim corridors, the eerie music (borrowed from RE2 ), and the character models — though low-poly — show Capcom’s ambition.
The Nintendo 64’s cartridge format offered near-instantaneous data loading. Capcom’s development team realized that swapping characters instantly on the PlayStation's CD-ROM drive would cause immersion-breaking load screens. In late 2000, Capcom officially halted production on
While the Sony PlayStation relied on CD-ROMs, which suffered from notorious loading times, the N64’s cartridge format offered near-instantaneous data loading. This speed was critical for Capcom’s ambitious new gameplay mechanic: .

To understand why the N64 prototype is so fascinating, you have to look at the hardware limitations Capcom was fighting against. Unlike the PlayStation, which used high-capacity CDs to store compressed video and pre-rendered backgrounds, the Nintendo 64 relied on expensive, space-restricted cartridges.
Running the prototype in an N64 emulator (like Project64 or MAME) reveals a rough, unfinished build:
