How to use the codes

1. Confirm the region, serial/Game ID and CRC where shown.
2. Make a separate backup of the save.
3. Add one complete block using the exact cheat format listed above in a compatible emulator or original cheat device.
4. Load gameplay before pressing any activation buttons.
5. Confirm the effect, then disable persistent or unlock codes before saving unless the instructions say otherwise.

Troubleshooting

The cheat appears but does nothing

The most common causes are a region/revision mismatch, the wrong cheat type, a missing enable code, or pressing the activator before gameplay loads. Disable every other cheat and test a single block on an unmodified dump.
