Some purists argue that GameShark codes ruin the "wander" of Front Mission 3 — the joy of discovering a rare Atsushi SG from a downed enemy commander. And they're correct, for a first playthrough.
However, for the 2024-2025 player revisiting this classic, the "all weapons" code provides something the original developers never intended: pure creative freedom. You can now build a squad of four Wanzers armed exclusively with shotgun-GR combos. You can give a missile backpack to a melee specialist. You can test damage formulas on the training map without spending 40 hours farming.
The codes listed here are the result of the community's 20+ years of reverse-engineering Front Mission 3's memory map. They are safe, effective, and transform the game from a grindy tactical sim into a sprawling mecha combat sandbox. front+mission+3+gameshark+codes+all+weapon
Solution: You have a corrupted weapon entry (e.g., a Backpack ID in a Handgun slot). Use a single-category code instead of the blanket FFFF code.
For any GameShark code to function on Front Mission 3, you must enable the Master Code. Without this, the weapon codes will not activate.
Master Code (NTSC-U):
800A1824 2402
800A1826 0000
D00A1824 2401
800A1824 2400
Enter these four lines together. Some GameShark versions require only the first two. If you experience crashes, try disabling the bottom two.
Backpack weapons are technically not “held” weapons but are treated as equipment. This code activates all GR Backpacks (grenade launchers) and Attack Repair Backpacks.
300ADF40 00FF
800ADF42 FFFF
300ADF44 00FF
800ADF48 FFFF
800ADF4C FFFF
What this gives you: MGR-6, GR-12S, and the legendary “Repair Backpack G” which can both heal an ally and fire plasma missiles. 8005B46A FFFF 8005B46C FFFF 8005B46E FFFF
Before diving into the hexadecimal strings, let's address why a player would seek these codes:
Weapons are nothing without the skills and parts to use them. Pair the all-weapon codes with these for a true power fantasy.
