Part 1 of the Pokemon Emerald rom hack, Pokemon Inclement Emerald. The video covers the intro and making from Littleroot Town to Rustboro City.
Note: As the title suggests, this is done using only Psychic type Pokemon. Special credit goes to the youtuber Michah the light paladin (https://www.youtube.com/channel/UCRxIZy5eHHDZ_pHDOAzKlGw) as it was his mono psychic videos of the game that gave me the hope that I could try it myself. Sadly, I did leave the difficulty on normal, but left it on set mode and planned on showing off as much post game as possible. In the version that I played, the Battle Frontier was not available and certain things, such as the gift Meloetta, wasn't implemented into the game. Lastly, alot of Pokemon had their typing and stats changed in this game, so some pokemon used pre-evolved may not have the psychic typing in it, the final evolution will. Also, I did miss some Pokemon early on (Swoobat and Pichu for example), I was unfamilar with the encounter routes at the time, so apologies for that.
