If you wanna be the very best, like no one ever was, these might be the games for you.

Note: Like the Final Fantasy series, when it comes to localization, the Pokémon games have been met with much confusion. As a result, this page covers the initial Japanese versions, titled Red and Green, the updated Blue revision, and the subsequent international localizations (confusingly dubbed Red and Blue) that drew from the latter.

Exits

Celadon House

An unused warp exists in Celadon City where the door to a house would be, but the door is not found in the final game. The warp leads to the fifth floor of the Celadon Department Store (map 136).

Since it would be unreasonable to end up on the fifth floor of somewhere from Celadon City and not the first floor, it may suggest that map 136 was altered at some point in the game's development. Further supporting this theory, the other floors (in order) for the Celadon Department Store have index numbers 122-125 respectively. The fifth floor (map 136) does not follow this pattern.

Exit location data exists for the map (the exit point index number is 08).

You can create a door to access the warp with the GameShark code 017C72C8. You can appear where the warp is by using the GameShark codes 0108B5D3 0108B1D3, entering a certain map in Celadon City (such as the Pokémon Center) and exiting.

Music

Unused Song

Game Genie Code	Offsets to Patch
132-2FB-F7D	0x822F to 13
692-30B-7F7	0x8230 to 69
CF2-32B-917	0x8232 to CF
692-33B-4CB	0x8233 to 69

Red and Blue both contain a short unused song with no defined pointers. The song appears to be incomplete, as it only has two channels whose octaves are set too high. In the ROM, the song's tempo is defined, being relatively quick. The two channels are located in the ROM at offsets 0xA913 and 0xA9CF. The ditty can be patched into Pallet Town by using a Game Genie code or manually patching a set of offsets, both displayed at right.

A fan-restored version of the track provides an example of how the song might have sounded:

Unused Type

While Flying-type Pokémon are familiar to fans, Generation I and II also feature an unused Bird type. It has no weaknesses or resistances, and is only applied to MissingNo.

Oddities

Pokémon Cries

For some reason, Ditto and Poliwag share the same cry, as do Charizard and Rhyhorn; the only Pokémon in the Gen I and II games to do so, with the exception of MissingNo.
