July 31 (UPI) -- A long-lost Pokémon game that was only available for a brief time in Japan in 2005 may have resurfaced on a Nintendo DS test cartridge for sale on eBay.

The eBay listing, which is from a German seller and starts at $9,145.66, was flagged by fans online as possibly being a surviving physical copy of Pokémon Fishing Contest DS.

The game was available as a download-only title at Japanese Pokémon Center stores from May-August 2005, and the game would delete itself from a system once it was powered off.

No playable copies of the game are known to still exist.
