Game Boy Overview

System: Nintendo Game Boy (Black & White)
Game Title: Multiple

I'm finally finished searching for push-button type cheats for the Game Boy.
I used the scanning method 'Increased Value By 1' on Title Screens and Pause Menu's.

If anyone would like to further search this system, I would scan using a different method.

These are almost always the hex value's for the buttons in RAM/ROM:
0x40 - Up
0x80 - Down
0x20 - Left
0x10 - Right
0x01 - A
0x02 - B
0x04 - Select
0x08 - Start

Opcodes:
