Advance Wars Game Boy Adv Glitches

Field Training Glitch - Unlimited Map Editing

With this glitch you can edit Campaign and War Room maps. The changes are saved only in the in-game (during battle) save, not permanently in the cartridge.

- Go to Field Training and play the Naval Forces mission.
- Lose by letting Olaf destroy either your T-Copter or your Lander.
- Go to the Design Maps, deploy an Orange Star unit and destroy it.
- Your screen will be glitched now. You can go to a saved Campaign or War Room map and edit it. Don't forget to save the changed maps using the in-game save, not the Design Maps save.
- To return to normal, just turn on/off the GBA.
