Capcom nearly shipped an entire PlayStation game on a Game Boy cartridge. That sentence sounds like a fever dream, but it very nearly happened, and the story of how it fell apart is one of the most fascinating footnotes in Resident Evil history.
The series has always had a complicated relationship with Nintendo hardware. Everyone remembers the GameCube era fondly, and for good reason. The Capcom Five, the Resident Evilremake, RE4 as a timed exclusive , that partnership produced some of the best games in the franchise. But the road to that golden age was paved with cancelled ports, dead peripherals, and at least one very disappointing decision by someone described only as one of Resident Evil's "original creators."
The Game Boy Color Port That Got This Close
In 1999, Capcom hired a small London-based studio called HotGen to squeeze Resident Evil onto the Game Boy Color's 2.3-inch screen. The GBC ran on hardware designed in 1974. Its display handled 56 colors at 160x144 pixels. The original Resident Evil shipped on a 514 MB CD-ROM.
HotGen chose to attempt an almost direct conversion rather than reimagine the game for the platform. The team recreated hundreds of Capcom's pre-rendered backgrounds for the tiny screen, with characters that scaled dynamically based on depth and distance. By any objective measure it looked rough. By the measure of "we just crammed a PlayStation game into an 8 MB cartridge," it was genuinely astonishing.
The project reached near-completion before Capcom cancelled it. The official reason cited concerns about the final product's appeal, and one developer later hinted that one of the series' original creators felt the port wasn't worthy of the source material. Whatever the internal politics, the game disappeared.
It didn't stay buried forever. An incomplete build leaked in 2011. Then, in December 2025, preservation site Games That Weren't surfaced a 98% content-complete build provided by assistant programmer Pete Frith. Missing only a few months of polish, the build is fully playable from start to finish. Jill Valentine's entire campaign, Spencer Mansion to Tyrant fight, is right there.

Capcom replaced the cancelled GBC port with Resident Evil Gaiden in 2001, an original title developed by M4 and set on a cruise ship. It's largely forgotten today, overshadowed by the Game Boy Advance launch that same year.Resident Evil 0 and the Peripheral That Sank
While HotGen was wrestling with the GBC, Capcom's internal Studio 3 had an even more ambitious project in motion. Resident Evil 0 was conceived as a Nintendo 64 exclusive, specifically for Nintendo's ill-fated disc drive add-on, the 64DD.
The vision was genuinely exciting. The 64DD's read/write capabilities would expand the "zapping system" from RE2, letting dual protagonists Rebecca Chambers and Billy Coen interact with the world in new ways. No bottomless item boxes. Drop your gear on the ground and hope you find it later, a callback to series ancestor Sweet Home. Local co-op from the same couch. Zero loading screens.
Then the 64DD failed spectacularly, and development shifted to the base N64. The team redesigned around the platform's storage limits, cutting cutscenes and leaning into a leaner, faster experience with quicker zombies and instant character switching. The game was real enough that footage screened at E3, a demo ran at Tokyo Game Show 2000, and a Japanese variety show featured an early build on a prototype cartridge.
It was around 10% complete when the GameCube changed everything. Capcom's partnership with Nintendo's "Project Dolphin" gave Studio 3 the breathing room they needed. The scenario and characters survived two platform switches, the game shipped on GameCube in 2002, and the running zombies concept quietly migrated over to the 2002 remake.
The N64 prototype itself? Almost certainly gone. In 2018, a collector found a developer cartridge with a "BIOHAZARD 0" label hidden under a Mega Man 64 sticker, the EEPROM long since overwritten. Tantalizingly close, and then nothing.
Where the Series Landed Instead
The path from those failed ports to today looks almost like a redemption arc. Resident Evil: Deadly Silence on DS delivered the original game with touchscreen gimmicks in a new Rebirth mode. Revelations on 3DS proved full survival horror could work on a handheld. And now, with the RE Engine running on hardware like the Steam Deck, the modern trilogy including Biohazard, Village, and the upcoming Resident Evil Requiem, confirmed for release on February 27, 2026, is even playable on Switch 2.
The GBC port and the N64 RE0 are fascinating artifacts of a franchise that kept swinging even when the hardware wasn't ready.
