One Bidder Puts $25,000 on a 1998 Pokémon Red Prototype

For collectors of vintage video game hardware, a single high-value bid has set the stage for a potential price surge in the coming days. As of this week, one buyer has committed $25,000 to a prototype version of Pokémon Red for the Nintendo Game Boy. The item is currently listed at auction, and while the final deadline is still several days away, the current standing suggests a strong market for this specific piece of history.

The cartridge dates back to 1998, the year the original game was released. It was first identified by the retro gaming community through Retro Dodo, which characterized the item as incredibly rare. The listing is managed through Goldin, where specialists at PSA Grading performed a physical and digital inspection. They were able to read the first 32KB of the data contents, a portion that PSA described as technically unique compared to standard releases.

Despite the unique opening bytes, the grading experts noted that the rest of the game data appears completely identical to the U.S. retail version. They expressed confidence that the unreadable sections of the memory would also match the final product. However, the report highlighted two specific deviations in the ROM header data. These differences do not impact the actual gameplay experience but are visible in the technical metadata.

One error is located at offset 0x014C, which indicates the mask ROM version. In this prototype, the value is set to 55 instead of the standard 00. This change alters the calculated header checksum at offset 0x014D, which reads CB rather than the expected 20. Physically, the device bears a sticker with the code DMB-MBC-16M-FLASH. Experts believe DMB refers to Dot Matrix Game, the internal codename for the Game Boy, while MBC likely stands for Memory Bank Controller, a component that allowed games to exceed standard memory limits.

The auction materials describe the internal board as a previously undocumented development tool, although the part number DMG-(F)KGDB-01 has appeared in other records. The Rare Gaming Dump wiki lists this same number for a 2000 development cartridge that used a similar 16-megabit Sharp flash chip. Images from the listing show a design that is nearly identical to that earlier entry, though the sticker text varies slightly.

Pokémon Red, which launched alongside its counterparts, played a pivotal role in establishing the global franchise during the 1990s. Combined sales for Red and Blue are reported to have exceeded 31 million copies. A reader comment on the original report suggested this specific unit is a master copy that remains fully playable. The commenter also linked the item to a batch of demo cartridges sold in 2015 by a Nintendo employee who retained them rather than discarding them, though these details have not been independently verified.
