With the GameCube's announcement, Capcom opted to restart development on the newer, more powerful disc-based hardware. Partner Zapping:
Capcom originally designed Resident Evil 0 as an exclusive title for the Nintendo 64, taking advantage of the high-speed data loading capabilities of the N64 cartridge format. Why the N64?

For years, it was considered one of the "holy grails" of lost video game history: Resident Evil 0 for the Nintendo 64. Before Rebecca Chambers and Billy Coen graced the Nintendo GameCube with stunning pre-rendered backgrounds and intense action, the game was fully intended to be a 64-bit horror experience.
Initially, Resident Evil 0 was targeted for the 64DD. But the peripheral was a commercial failure, delayed repeatedly and ultimately released only in Japan, where it sold poorly. When Capcom realized the 64DD would never be a viable platform for a global release, they were forced to pivot back to the standard cartridge. This led to a massive compression effort. In the final N64 build shown at TGS 2000, the "Zapping" system and unique item-dropping mechanics remained, but the game was likely heavily cut down from its original vision to fit on a cartridge with a fraction of the storage space of a CD-ROM.

While the story beats closely mirror the final 2002 GameCube release, the prototype features distinct atmospheric choices. Rebecca Chambers wears her classic, bulkier S.T.A.R.S. uniform from the original Resident Evil , rather than the streamlined version seen on the GameCube. The user interface, inventory menus, and text fonts closely mimic the look and feel of Resident Evil 2 , giving the prototype a distinct late-90s Capcom aesthetic.

The N64 utilized cartridges, which offered fast load times but limited storage (64MB) compared to the GameCube’s mini-DVDs (1.5GB).
Capcom began developing Resident Evil 0 for the Nintendo 64 in the late 1990s. The game was designed to take advantage of the N64’s unique capabilities—specifically the high-speed data transfer of Nintendo 64 cartridges. Unlike the PlayStation, which required loading screens between rooms due to slow CD-ROM read speeds, the N64 cartridge could stream data instantly.
First, a direct port of Resident Evil 2 (which would become legendary for its compression—cramming two CDs onto one 64MB cartridge). Second, a brand new title called Resident Evil 0 . Third, a mysterious third entry, Resident Evil (N64 Version) , which would eventually morph into Resident Evil: Gaiden for the Game Boy Color.
