Overview

PokéPark Fishing Rally DS is a downloadable Pokémon fishing game for the Nintendo DS from 2005.

It was only offered at two events and Japanese (and maybe Taiwanese idk) Pokémon Centers for a limited time.

To my knowledge and at the time of writing there is one known ROM dump of this game, and it's privately owned and not available online.

...So here's all the other interesting info I could find!

ROM History

https://web.archive.org/web/20050920064212/http://akkit.org/DS/E3/

The demo was captured by an anonymous person and assembled into a .nds rom by firefly. This information was posted between August 24 and September 20, 2005.

Based on the footage I'd say this rom is most likely the Japanese Pokémon Center version.
