Pokémon Red, Green, and Blue

pokejp serves as a dissassembly base, based on the Japanese releases of the Generation 1 Pokémon games.

It builds the following ROMs:

Pokemon Red.gb
Pokemon Green.gb
Pokemon Blue.gb

Downloading and playing

In the case of simply wanting to play generation 1 as it was released in Japan, download the .ips patch files from the patches folder, and use a tool like Lunar IPS (for Windows), MultiPatch (for OS X), or UniPatcher (for Android) to apply the patch to the correct ROM.

These are the roms you should use for each version:

Red

Pokemon Red (UE) [S][!].gb sha1: ea9bcae617fdf159b045185467ae58b2e4a48b9a

Green and Blue

Pokemon Blue (UE) [S][!].gb sha1: d7037c83e1ae5b39bde3c30787637ba1d4c48ce2

They're based off of the ones made by the pokered project.

Why make this?

In 1996, The original Pocket Monsters Red and Green were released. Later that Year, Pocket Monsters Blue was released as well. In the west, 2 years later, Pokémon Red and Blue werre released, using the updated Pocket Monsters Blue as the base engine. A Pokémon game with Pocket Monsters Blue's wild data was never released in Japan. This caused a multitude of changes in the International releases of Red and Blue. This ROM hack serves to create English Versions of those Japanese releases, without including the game breaking glitches in those games.

What's changed?

Any bugs present in the original Red and Green that are not in the International Red and Blue are not present.
The title screen of Pokemon Red and Green has been changed to the original Japanese release.
Pokémon Blue's wild Pokémon data has been edited to the Japanese release. Pokémon Green uses US Blue's wild data.
Pokémon Red and Green now use the original Cerulean Cave layout.
Pokémon Red and Green use their Overworld and Pokémon graphics from their original release.
Pokémon Green loads its unique Super Game Boy Palette.
Each game's Super Game Boy Border now has text saying "POKEMON!" where "POCKET MONSTERS!" normally is in the Japanese games.
Fixed Glitch where Haunters from in-game trades wouldn't evolve.
