Poké-preservationists have potentially found an incredibly rare game. A listing recently appeared on eBay (via IGN) that seems to be related to PokéPark Fishing Tournament DS, a game that was never released outside of Japan. It was available exclusively at Pokémon Centers and other Pokémon pop-up events, including Pokémon The Park, a short-lived theme park that operated for a few months in 2005.

In the game, players could catch all kinds of Poké-fish and would win points based on the creature’s weight, level, and rarity. There was also a leaderboard function that would transmit a player’s score to be displayed at Pokémon Centers. While the game is no longer available, you can see it in action over on YouTube:

The game is technically lost media as it was only ever available via download and would delete itself from the user’s DS when the handheld was powered down, making the game a preservationist’s worst nightmare. While the listing is going for roughly $9,100 USD, Poké-lore hounds aren’t sure if the game itself is on the cartridge.

The biggest reservation the preservation community has is this mention of a âsub-cardâ.

There is a very good chance that the actually fishing rally may have been stored on a GBA cartridge & what we see here was only used to share the game wirelessly and/or accept leaderboard⦠pic.twitter.com/sFBgsuHdzX

The listing states that when the cart is put into a DS, a Japanese-language screen comes up, “indicating a high-score ranking communication program,” lending weight to the idea this actually isn’t the game but some technical cart used to manage the game’s wireless capabilities. Still, some members of the Pokémon community hope that one of their own can get their hands on the cart instead of someone who might lock it up as a part of a private collection.

Professor Rex, the Pokémon fan who leashed together a whole bunch of consoles hunting for an elusive golduck shiny, has suggested organizing a group of people to buy the cart for preservation purposes.

If youâd consider chipping in on a group-buy to preserve the software please DM me ~ Iâm not sure if we would have any chance to get this before it goes to a private collection but we may as well try ð

They’ll need a big chunk of change if they plan to do so. The eBay listing currently has the auction price of the cartridge at roughly $9,104. And that’s before anyone even knows what’s truly on it.
