Follow this guide to replace, upgrade, or customize the back shell (aka rear shell or back cover) on your Nintendo Game Boy Advance model AGB-001.

If you're completely re‑shelling your Game Boy, follow this guide.

The Game Boy Advance uses JIS screws. If you use a non-iFixit Phillips driver in JIS screws, you'll risk stripping them. iFixit's Phillips bits are designed to be compatible with JIS screws.

If you have a game cartridge installed, remove it.
