Master Code
As with all games, before inputting any other codes, the Master Code for the game has to be input. This is the code that allows other codes to be used. The Master Code for "Dragon Quest VIII" is "FHDV-CFVM-P8GHF 2Z16-8X1P-HT7VV."
Maximum Weapon Strength
Weapons in "Dragon Quest VIII" are not at their full power when first picked up. They must be grown through experience and care throughout the game, and focusing too heavily on developing one weapon can lead to others becoming under-powered when the time comes to use them. Input the code "XRT0-FEN2-H3GPC R5WF-8DBR-DWM8P FNRA-Q61Z-9HPVY" to get weapons with the maximum strength, durability and defensive power for every character, as soon as you first use the weapon.
Maximum Weapons
In "Dragon Quest VIII," swords, spears, boomerangs and fist-attacks diminish through use. Running out of boomerangs in a battle with flying enemies, or swords in a fight with an enemy who will battle using nothing else, can make progressing in the game difficult. Action Replay codes can be used to get you the maximum number of these weapons, ensuring you never run out at a crucial time. Enter "Q14B-NKFV-04KCU WBEX-9DD4-THD93" to get the maximum number od swords. "KY3V-BGFE-MT1R3 2B64-8TN7-MJQ67" grants the maximum number of spears, and "YX6W-AR9U-0EWZB 5TNW-DFTU-5F3JC" the maximum number of boomerangs. Get maximum hand-to-hand attacks, called fistycuffs in the game, by entering the code "NEWF-RB1X-XG7Y1 XMR2-K2T5-EWUCE" on your Action Replay.
