WarioWare D.I.Y. Editor

Game Specific


A MIO and save editor for WarioWare D.I.Y.


  • Extract and import MIO files from WarioWare D.I.Y and WarioWare D.I.Y Showcase savefiles
  • Modify save file to unlock medals, games and comics
  • Edit microgame/record/comic header
  • View game preview picture and background
  • Play records and export MIDI.
  • Read comics.

bobmcjr has written back-end code for the music editor but cannot come up with a good interface for it. If anyone could write something in java that looks roughly like the D.I.Y. music editor he would appreciate it. The source is included in the download.

Note: This program only works with save files that are 32MB even though raw WarioWare D.I.Y. save files are 16MB, as the device bobmcjr used to transfer save files saved them in that size. This can be worked around by padding a raw save file with 16MB (0×1000000 bytes) of zeroes in a hex editor.

Decent Preservation Tool

Reviewed By: wildgoosespeeder on 25 Sep 2016

This tool is simply amazing! Once you find the levels that were officially distributed by Nintendo (NinSoft), you can play the Microgames beyond the Nintendo Wi-Fi Connection shut-down May 20, 2014 if you buy the game new or used and start over (if you have the methods that can overwrite the save on a real DS card). For emulation, fast feedback.

I do have a few nitpicks though. The item injection GUI could use some work. For whatever reason, the tool refuses to add/remove/overwrite the 90th slot. You have to go in-game to force an item into the 90th slot so that way you can cram 90 of each type of item (89 more inserts). Also, you can select all in the lists but can only delete one at a time.

Otherwise, this is a must-have tool for anyone that likes to play WarioWare games that has D.I.Y DS card and/or WiiWare titles in their collections.
