PSA Authenticates Long-Lost Pokémon Fishing Rally DS Game From 2005 PokéPark

A Pokémon Nintendo DS game that was never commercially released and had been considered lost media for roughly two decades has resurfaced, with PSA authenticating and encapsulating a physical cartridge of PokéPark: Tsuri Taikai DS, better known as PokéPark: Fishing Rally DS.

PSA detailed the discovery after one of its researchers was given an opportunity to examine and actually play the game before the cartridge was submitted for authentication. According to PSA, Fishing Rally DS was available exclusively at the PokéPark theme park in Japan during the summer of 2005 and later in Taiwan during the summer of 2006. After those events ended, the game was never released commercially and its software was not made available online, leaving it regarded as lost Pokémon media for approximately 20 years.

PSA researcher Claire Shelton said she met with the cartridge’s owner in early September 2026 and spent roughly two hours discussing the physical game, its origins and the software itself. Rather than relying solely on the cartridge’s exterior or documentation, Shelton was able to play through the fishing game firsthand before the item eventually entered PSA for authentication and encapsulation.

The game centers on catching Pokémon across different fishing areas, with players moving between fishing zones and accumulating points through a scoring system unique to the title. Shelton compared the basic fishing gameplay to fishing mechanics found in games such as Animal Crossing and Harvest Moon, while noting how unusual it was to play a Pokémon title for which so little documentation is available online.

Among the Pokémon Shelton encountered was Relicanth, which she described as her favorite catch during the session. The game also includes Pokémon that appear in the backgrounds of the fishing locations but cannot be caught, including Psyduck, Politoed and Slowbro. Shelton ultimately recorded a score of around 25,000 points during her time with the game.

That scoring system also connects the surviving game to another unusual piece of PokéPark hardware. PSA says scores could be transferred to a high-score kiosk at the theme park, but doing so required a separate, unique cartridge. PSA has since authenticated and encapsulated one of those high-score transfer cartridges as well, submitted independently by another owner.

PSA did not disclose the identity of the owner, the cartridge’s current value or exactly how many examples are known to survive. The company did, however, describe the authenticated cartridge as one of the only remaining ways to interact with the formerly lost Pokémon game and said its authentication helps preserve the item while also giving future collectors additional confidence if it is ever sold or transferred.
