Actually they don't. Although the Gameboy processor is similar to a z80, it
has many differences, most notably the absence of the shadow registers and
interrupt codes. There is also no more ldir or cpir. Instead you can do
things such as this:
ldi a,(hl) ;ld a,(hl) \ inc hl
swap a ;swap nibbles in a
ldi (de),a ;ld (de),a \ inc de
ld ($ff00+$e0),a ;2 byte instruction!
NOT exactly the same processor...
