Pokémon Emerald is an updated version of Pokemon Ruby and Sapphire, that was released in Japan in September 2004 and in America and Europe in 2005. Even if the game is just an “add-on” to Ruby and Sapphire, it’s possible to find some beta and unused content still hidden in its code. As noted by Bulbapedia:
Also, from an early Pokèmon Emerald screenshot by IGN you can clearly see that ROUTE 109 had glitched up tiles!)

In the ROM LucaPM found an unused Prof.B irch sprite, that was probably used for the beta intro sequence. HEX Offset : 557AF0 (varies between ROMS)
Unused sprite:

Final sprite:

Things to notice between the unused and the final sprite:
As noted by Zero7, it’s possible that he was suppose to have his hands in his pockets, go into the now final sprite for throwing out the pokemon, then either stay in the final sprite or back to the unused sprite for the rest of the intro.
U64 is an archive with articles, screens and videos for cancelled, beta & unseen videogames. Every change & cut creates a different gaming experience: we would like to save some documents about this evolution for curiosity, historic and artistic preservation.

The other thing is that in the picture of route 109, the text window doesn’t stretch to the width of the entire screen, as it does in the final.

What about the unused Team Rocket music? In fact, the only way to play it is to activate the “fatalerror” glitch. (Game can’t find a hex code for music)

By the way,the fatal error glitch Internet was talking about happens when you pull the cartridge halfway out.
