Tweaking

Tweaking is a glitch that first appeared in the fourth generation of Pokémon. It is caused by pressing the left and right buttons continuously whilst holding the up/down button and riding on a bicycle in fourth gear. It is most easily done in Jubilife City. This glitch will throw up invisible walls or cause a section/route to become black, only seeing the shadows of trainers, items etc. Tweaking seems to have no negative consequences on the game's data.

According to some, tweaking may allow players to catch Arceus, Shaymin, and Darkrai; however, this is unconfirmed.
