Game Boy History: Prototype Pokémon Red Cartridge Faces $25,000 Bid

A pre-release prototype of Pokémon Red for the Nintendo Game Boy has entered the market with a single bid of $25,000. The listing on the Goldin auction page features a development unit that dates to the game's 1998 release. Retro Dodo first identified the item and described the artifact as incredibly rare for collectors of retro gaming hardware.

Specialists at Professional Sports Authenticator authenticated the cartridge but could not execute a complete data read. They successfully read the first 32KB of the contents, a result the company labeled technically unique. PSA stated that the readable game data is completely identical to the U.S. retail version. The firm expressed confidence that the unreadable remainder of the data would match the standard release.

The authentication report identified two differences in the ROM header data that do not affect gameplay. One discrepancy appears at offset 0x014C, which denotes the Mask ROM version. That value is incorrectly set to 55 when it should be 00. This change alters the calculated header checksum at offset 0x014D, which reads CB rather than 20.

Physical inspection of the cartridge reveals a sticker reading DMB-MBC-16M-FLASH and the part number DMG-(F)KGDB-01. The report suggests DMB likely refers to Dot Matrix Game, the original internal codename for the Game Boy. MBC likely stands for Memory Bank Controller, a custom chip that allowed games to exceed the console's standard 32KB ROM limit. The 16M designation probably indicates 16 megabits of flash-writable memory. The unit is physically longer than a standard Game Boy cartridge.

The auction describes the board as previously undocumented, though the specific part number has appeared in other records. The Rare Gaming Dump wiki lists the same number for a 2000 development cartridge that used a 16-megabit Sharp flash chip. Images in the Goldin listing show an almost identical design, but the wiki entry displays a slightly different sticker reading DMG-MBC3-16M-FLASH.

Pokémon Red launched the global franchise in the 1990s. Red and Blue combined have sold more than 31 million copies. A commenter on the original report claimed this specific copy is a master version that powers on and plays normally. The commenter also noted that similar demo cartridges surfaced in 2015 from a Nintendo employee who kept them rather than destroying them. Those details remain unverified.

Several days remain before the auction closes. The current bidder holds the high mark at $25,000, and the final price may increase before bidding ends.
