This mod transforms the visual appearance of cards in Yu-Gi-Oh! Master Duel by applying the card frame style used in Yu-Gi-Oh! Rush Duel. It repositions and rescales various card elements to match the Rush Duel aesthetic, including card artwork, level indicators, text areas, and attribute icons.

• Card Frame Transformation: Converts Master Duel card frames to Rush Duel style
• Element Repositioning: Automatically adjusts positions of:
  • Card artwork (moved and scaled)
  • Level stars (hidden and replaced with a numeric display)
  • Card name positioning
  • Effect text area
  • ATK/DEF values
  • Attribute icons
  • Spell/Trap type indicators
• Level Display: Replaces traditional level stars with numeric level display

• Yu-Gi-Oh! Master Duel
• MelonLoader
• .NET Framework 6 support

1. Install MelonLoader for Yu-Gi-Oh! Master Duel
2. Download the latest release in the releases tab
3. Place the MasterFaceEditor.dll file in your MelonLoader Mods folder
4. Replace the card frames and masks in the game with the ones provided in the res folder
   • The release includes a GUI app to automate this process, but it can be done manually as well
     • The GUI app source code and the card frames can be found in the installer repository
   • This can also be done manually with a GUI modding tool, such as Floowandereeze & Modding
   • Alternatively, you can manually replace the assets in the game's data.unity3d file using a standard Unity Modding tool, such as UABEA
5. Launch Yu-Gi-Oh! Master Duel

The mod automatically applies the Rush Duel card frame style when viewing cards in-game. No additional configuration is required.

• Some card types may require additional positioning adjustments
• The card frame replacement may need to be redone after major game updates
• The Pendulum Monster frame cuts a lot of the card artwork off, so some cards may look a little off

• Adapt Link Monsters to use the proposed design from Phanthelia's Template
• Adapt Pendulum Monsters to use the proposed design from Phanthelia's Template
• Change Spell Cards so they have their type written instead of an icon, as they currently do in Rush Duel
• Make the mod automatically replace the card frames in the game's data.unity3d file

The .csproj file must use the references from your Master Duel MelonLoader folder.

• The project uses Melon Loader as the modding framework
• Harmony Patcher is used for patching some methods in the game code
• Currently, development is focused on Windows, as that is the main supported desktop OS for Master Duel
