DQMJ1 ROM Editor

An unofficial modding tool / ROM editor for Dragon Quest Monsters Joker 1.

Currently only supports the North American and Japanese releases of the game, but I may add support for the European release at some point.

Features

Currently supports modifying:

• Encounter tables (enemies, bosses, starter monsters, gift monsters)
• Skill sets
• Events (cutscenes, overworld areas) [experimental]

Documentation

For information on how to use the ROM Editor, see:

• User's Guide - tutorials on how to edit encounter tables, skill sets, and events

Note that the ROM editor currently only supports Windows and Linux. I may add Mac support if there is interest.
