I know that this isn’t a new mod or anything, but I just took pictures of the process along the way anyway. After desoldering the old battery, you can put in the battery holder. It’s just a slight bit to wide, so you’ll have to bend the tabs inwards. Just solder it in afterwards! And that’s basically it. Put in a new battery and never worry about the systems clock anymore :)

    Neat. I did this to my copy of Pokémon yellow. Convenient mod.

      Yeah, it’s a great mod for the many consoles/cartridges that are affected. But it seems like there isn’t enough space for something like this in GBA cards. Unfortunate, I love the GBA.
