Pokémon Ruby and Sapphire beta

Several things were originally going to be added to Pokémon Ruby and Sapphire Versions during the time of its development. Some were dropped or changed, and some of the dropped concepts of the beta can still be found in the game's programming.

Team Aqua sprite

Unused Team Aqua sprite

What appears to be an alternate model of a Team Aqua Grunt, Aqua Admin or even a beta sprite of Archie has been discovered in the coding of Pokémon Ruby and Sapphire.

Beta music

Some remastered Generation II music exists, inaccessible in the coding of Ruby and Sapphire. Known pieces include:

BGM used on Routes 38 and 39
BGM used in the Pokémon Communication Center
BGM used in Saffron City during Generation II
BGM used in battles with the legendary beasts in Pokémon Crystal
Team Rocket's theme

All of these themes came from Pokémon Gold, Silver, and Crystal. These may either be early pieces of music used as stand-ins, or may have hinted at the developers having an intent to make a remake of Gold and Silver instead of one of Red and Green, or even including Johto and/or Kanto, à la Gold, Silver and Crystal. There are also four other variations on the Contest music.

Pokédex sprite

What appears to be a beta model of the sprite that is used for a Pokémon the player has not seen is two blocky, big and white question marks instead for the round and black one with a white circle and a white question mark.

Abilities

An ability known as Cacophony was found within the games programing; however, no Pokémon have it (unless hacked). It is identical to Soundproof, another sound-based ability, and it allows the Pokémon to avoid all sound-based moves. Since it is identical to Soundproof, it may have been meant for the game, but the programmers decided to put Soundproof in instead.

Pokémon

In an interview in Nintendo Power, it was revealed that Shellos and Gastrodon were originally designed for Generation III instead of Generation IV. These are not the forms in the final versions however; Diamond and Pearl's programming code reveals a back sprite for both Pokémon, but no front sprite. Shellos's sprite is pink, like its west sea variation, and seems to combine the western variation's head with the eastern variation's body, while Gastrodon's sprite is brown and looks like its western variation, but with more rock-like protrusions on its body.
