The "Extinction" Theory: Industry reports suggest that many of the original EEPROM development cartridges were overwritten for other projects, such as a Mega Man 64 prototype. This has led many preservationists to fear the original build may be technically extinct.

Collector Activity: Rumors persist within private circles about a surviving build valued at upwards of €30,000, though no reputable source has confirmed a successful sale or dump of such a cartridge to the public.

The mechanic of dropping items on the floor (replacing item boxes) was already present in the N64 prototype and was a core design choice intended for the system's architecture. Development History RESIDENT EVIL - ZERO PROTOTYPE (NINTENDO 64)

For two decades, the Resident Evil 0 N64 Prototype Rom existed only in blurry magazine scans. That changed in February 2018. An anonymous collector, allegedly a former Capcom employee from the Osaka branch, dumped the contents of a forgotten developer flash cart into the hands of the Obscure Gamers forum.
