This page details one or more prototype versions of Pokémon Mystery Dungeon: Rescue Team DX.

This article covers the demo version of the game.

To do:
Check if there is anything different from the final game
  • Is there any early graphics, sounds, animations and models in this build?
  • Any unused assets as well?
  • Interestingly enough, the demo does have some code for some cutscenes that are only meant to be playable in the final game. Being the recruiting part with Wigglytuff, you just need to bypass the dungeon limit via a save file from the final game after beating the Mt. Steel dungeon. In which possibly means the demo is actually the final game with missing files.
    • Try and mod it by putting the missing files to the demo and see if it plays like the full game. As there is some cutscenes from the final game in the demo.
  • Some of the files on this page are seriously low quality and need replacing.

Demo Lockouts

  • You can only explore two dungeons, Tiny Woods and Thunderwave Cave.
  • The game will not let you progress in the story after Dugtrio appears. All you can do at this point is train in the Dojo to level up your Pokemon.
  • You cannot recruit any Pokemon or access the Team Camps due to Mt. Steel and dungeon access being disabled.
  • Certain features are disabled in the demo such as:
    • Friend Rescue (Same goes for the post office)
    • Wondermail
    • Dungeon Exploring (After exploring two of the dungeons in the demo)

Differences Between The Final Game

The demo build was made on January 9, 2020. It is around 2 months older than the final build. It features a similar title screen to the full game, but with the word "demo" added. The demo logo is still left in the final game, unused. The file size for the demo version is reduced to 1GB, rather than 3.7GB in the final game.

Final Game Leftovers

A ton of stuff from the final game can be found in the demo's files, these are most of them but not limited to.

  • Animations, Models, and Portraits for story Pokémon that can only be seen in the final game.
  • Rescue Team Camps can be accessible via using a final game save file, although there is no music for it.
  • Additionally some cutscenes from the final game can be viewed in the demo version.
  • Pikachu's House Model can be found in the demo files.

Bypass Demo Lockout

There is a way to bypass the demo lockout by using a save file from the final version of the game. After you beat Mt. Steel, import the save to the demo version via Yuzu. You can see some cutscenes you are normally not supposed to see in the demo. Some cutscenes crash the game however, due to the demo missing the files required for the cutscenes to load. Dungeon exploration is also still locked.

Rescue Team Camps

Rescue Team camps are not normally accessible in the demo version of the game, however, they can be accessed from a final game save file being imported to the demo version. They function like the final game but with no music, due to the files for the music being missing in the demo.

Temporary/Unused Graphics

In-development screenshots of the game can be found within the demo’s files with the kanji for “Temporary”. They mostly are maps of boss arenas and dungeon-end areas from the original pair of games (some of which are crudely stitched together from multiple screenshots), most likely to help the remake team in designing the updated versions. Some strings of numbers appear at the bottom of a few of these images, probably debug information of some kind. The genshikaiki block is from a screenshot of a Windows Media Player video.

Amusingly, the cropping on the reference photographs isn't quite perfect, revealing that they were taken in an emulator.

Unused Files

A binary file entitled shiren_arts_data_info.bin is present in the demo's files. The name suggests a relation to Shiren the Wanderer, another Mystery Dungeon series developed by Spike Chunsoft. This file is still present in the final game.


Using A Save File from the final version of the game

Since the save file system is exactly like the final game, it is possible to use a save file from the final version of the game via Yuzu. However, the game will crash when you attempt to load it, as the demo is missing files required for certain things such as upgradeable buildings (Except for Pikachu's building, which is still in the demo's files).

Partner telling you to go to Mt. Steel

Despite the demo not allowing you to go there, your partner still asks you to check out Mt. Steel in the demo version.



The demo version has way more in-development stuff inside revisionDataLocal.xml that was later removed in the final game's revisionDataLocal.xml file.
