What is a prototype cart?
A physical cartridge containing an early, often incomplete version of a game used during development or demonstrations, not released to the public.
What is an unreleased build?
A digital version of a game in development that was never released to the public, typically seen by developers and testers or used in internal demos.
How do prototype carts differ from final releases?
Prototypes are unfinished, may have bugs or missing features, and are used for testing or demonstration; final releases are polished, complete, and widely distributed.
