Quality-of-Life Patches

Digimon World: Dawn and Dusk are both very charming games that also happen to have a set of very frustrating issues, the most glaring being how grind-heavy and slow-paced the games are.

If you've played these games before, chances are that you recall some of the most negative points:

• Being constantly underleveled and having to grind encounters endlessly to keep up with the pace of the game;
• Trying to reach an objective while in a dungeon and being completely swarmed with encounters;
• Feeling like the overall pacing of the game is too slow.

This tool aims to solve the above problems and provide a better game experience to everyone who plays this game, be it for the first time or as a re-run.

The following quality-of-life patches have been implemented so far:

Grinding Reduction

• Increased Exp Yield for Wild Digimon
• Increased Scan Rate
• Reduced Wild Encounter Rate

Pacing Improvements

• Increased Text Speed
• Increased Player Movement Speed

Misc.

• Expanded Player Name Length (from 5 to 7 characters)

Randomization Settings

The following randomization options have been implemented so far:

• Starter Packs
• Wild Digimon
• Digivolutions
• Digivolution Conditions

See this page for more details about the current randomization options and work-in-progress.

Known Issues

• Some antiviruses may flag the executable as unrecognized, as it does not have a signed publisher. This is expected behavior; proceed by clicking "Run anyway" to open the randomizer.
• If you have an existing save file for your game, the digivolution + digivolution conditions randomization may cause visual issues on your current save file.
• Similar to the above, the player name length expansion patch is meant for new-game roms. Loading an existing base-game save into a patched rom may also cause visual issues.

Acknowledgements

Most of the research work for this game was accomplished using HxD, DeSmuME and Ghidra.

The implemented user interface was heavily inspired by Universal Pokémon Randomizer's design.

Special thanks to:

• @Dreaker, who composed a set of thorough code notes for these games and has been supporting this project's efforts through brainstorming, feature testing and listening to me yap about ROM editing for hours [:
• @PocketRotom, who helped me generate the macOS application release and found a couple of very critical bugs right before the initial release 🙏
