The Nintendo logo is loaded from the cartridge header, and the Game Boy's firmware won't boot the game without it. So a truly "empty" program can't be run at all. Thus a minimum of a valid cartridge header is required for an empty program that the Game Boy can actually run.
The beginning of the cartridge header is a jump to the program's start. Simply duplicate this instruction at that address and voila:
<lang z80>ProgramStart:
jp ProgramStart</lang>
=={{header|Zig}}==
