The Doduo Game Boy allows you to play the specified version at double speed. The Dodrio Game Boy allows you to play Red/Blue/Yellow version at quadruple speed, or Gold/Silver/Crystal versions at triple speed. When these are unlocked, you must press C-Right to change the speed.
Notes:
- When you unlock Dodrio Game Boy, it doesn't tell you that it is unlocked, even though it is.
- When you play Gold/Silver/Crystal versions at least double speed, all colors will be shades of red, and the border will be missing.
- If you haven't beat the Elite Four in the G/S/C versions, this will not work in your game until you do so.
