Ultima: Quest of the Avatar is the NES port of the computer game Ultima IV: Quest of the Avatar. It is a traditional 4-person party fantasy RPG. You fight enemies to collect gold, buy better weapons and armor, and enter 3-D dungeons. However, unlike regular RPGs, there isn't a final villain to face. Instead, you try to become the embodiment of the eight virtues by doing good deeds throughout Britannia.

Character's inventory. Each character can hold 6 items.
See Item List for item lookup. Add 80 to the item to equip it.
6839-683E - Mage Inventory
683F-6844 - Bard Inventory
6845-684A - Fighter Inventory

Stats. Each stat has eight values.
The character order is: 0-Mariah, 1-Iolo, 2-Geoff, 3-Jaana, 4-Julius, 5-Dupre, 6-Shamino, 7-Katrina
So, if you want to adjust a stat, add the character value (times the number of bytes) to the initial offset.
For example: If you want to give Dupre the fighter 999 Max Hit Points, start with the Max Hit Point location (6881).
Dupre's character number is 4. Multiply by the number of bytes (2 in this cast).
So, the address is 6881 + 8 = 6889.
Enter the two-byte hex value of 999, E703. And Dupre will have 999 Max HP.
