Save exploit
Game-save exploit
The save exploit is the cheapest way into GameCube homebrew because it needs no hardware modification at all. You copy a specially crafted game save onto a memory card, load it inside a vulnerable game, and the malformed data tricks the game into running Swiss instead of continuing play.
What you need
- A supported retail game that has a save-loading vulnerability.
- A memory card with a tool such as GCMM (GameCube Memory Manager) used to write the exploit save onto it.
- A way to get the save file onto the card, often another homebrew-capable console or an SD adapter.
How it plays out
- The crafted save is written to a memory card.
- You start the vulnerable game and open its save/load screen.
- Loading the exploit save redirects execution into Swiss.
Strengths and limits
It is free and fully reversible, which makes it a great first step. The trade-off is convenience: you must own a compatible game, and you re-run the exploit each session unless you pair it with a more permanent entry point later. Many people use the save exploit once to install PicoBoot, then never need it again.
