| Dragon Warrior saves the hero as a 32-byte record in battery-backed cartridge RAM; bytes 0-1 hold experience, 2-3 gold, 4-7 the inventory, 8 the magic keys (capped at 6), 9 the herbs, 10 the equipment, 11-13 spell, player, and story flags, 14-21 the name, 22 the message speed, 23 HP, 24 MP, 25 whether HP and MP are refilled at the start, 26-29 the filler byte $C8, and 30-31 a check value. | 0x6-0x6 | Code |
| Rev 1 differs from the build of nmikstas's disassembly in three bytes of text and none of code; on its title screen "TRADEMARK TO NINTENDO" becomes "TRADEMARK OF NINTENDO". | 0x3FAE-0x3FAF0xAF7C-0xAF7C | Code |
| Measured in the ROM over all 65,536 generator states, with Agility 40 against a defense byte of 40, the hero escapes 87.70% of the time from the first group, 81.64% from the second, 75.20% from the third, and 50.20% from the fourth; the hero takes the first turn 87.70% of the time. | 0xEEA1-0xEF0C | Verified |
| Measured in the ROM over all 65,536 generator states, attack power 60 against a defense byte of 40 deals 10–20 damage, each of 10 to 19 in 25 of 256 rolls and 20 in 6; attack power 20 deals 0 or 1, half each. | 0xEFF5-0xF05F | Verified |
| Measured the same way, a monster's attack of 90 against defense power 60 deals 15–30 damage, and an attack of 20 against defense power 40 deals 0–4, mostly 1–3. | 0xF004-0xF05F | Verified |
