@GrantMeStrength Error: the Z80 was not used in the Nintendo Gameboy. It uses a mostly similar CPU from Sharp that we call the SM83. Opcodes are not quite the same, missing hardware, adds stuff.

@GrantMeStrength You could say the SM83 was inspired by the Z80 and 6502. It has a zero-page like area at the top of memory, accessible with shorter opcodes. No shadow registers or index registers. I/O is very different. Added a nybble swap opcode. But yeah, most Z80 coders would be both comfortable and frustrated by it.
