Pokémon Prism is a cancelled Rom Hack of Pokémon Crystal, created by Koolboyman. The storyline elapses in the region of Naljo. The game is a sequel of Pokémon Brown, thus, the player can travel to Rijon for a second quest. The Pokédex has 252 Pokemon, including some from each of the first four generations as well as new Elemental Types and TM's. The game includes new mini-games and plot points in which the player controls a Pokémon. The dev team of Twitch Plays Pokémon also contributed to the game's development with lead developer Koolboyman as project manager.
On December 21, 2016, Nintendo sent a cease & desist order which ended the game's development. However, an anonymous user on 4chan leaked v0.91 (build 0144) of the game, the leaked build is from December 19, 2016.
The current leaked build is fully functional, but is missing certain things from what would have been the finalized version of the game, such as outdated sprites, missing trigger events for trainers, and a post-game mission from Lance that was supposed to have been released in an official future build of the game. Version 0.93 is released, which fix most of the bugs in the leaked version. Versions 0.92 and 0.93 were developed by RainbowDevs who are the new development team for Pokémon Prism.
This is the story of Prism, the son/daughter of Lance. After playing in his uncle’s mine cart in an unidentified region, it somehow spins out of control and ends up in the region of Naljo. Naljo is a developing region bent on the dream of purist industrialization. After finding a lost Larvitar, Prism must collect the 20 Naljo badges while fixing all that is wrong with this corrupted region.
