The guy above me is so naive
There’s more than one gameboy emulator:
Rin/RinTest/Homer’s rin – (Best IMO) depending on which firmware you have.
And then there’s:
SpiceBoy
gpsp – Gameboy Advance only
and then there’s a few others. You’re better off getting one of the rin versions if you wanna play gb/c and a version of gpsp if you want to play gameboy advance
Oh yeah,
You must have a custom firmware.

No.
