Has a long way to go. Many errors here, and any true fan or historian of Nintendo would see them immediately.

The startup screen is the Game Boy Advance, not Color.

The Pokemon center building is completely messed up.

The sprites are a bizarre and somewhat inaccurate mishmash of the RBY and GSC games. Only GSC were coded with GBC colors (Yellow was a bit of a middle ground, Red and Blue were only GB coded)

At least he's saying Game Boy and not the incorrect "Gameboy" that most people type wrong.
