Delta GBA Cheats

I know Delta might be a bit taboo around here now but does anyone know how to make Codebreaker cheats work on its GBA part? I was playing the first Battle Network game on Switch through the Collection and made the mistake of believing they added autosave and had to start from scratch after dying in the power plant due to bad battery in-game and I REALLY do not want to grind again.
