Yu-Gi-Oh! ZEXAL World Duel Carnival
Uncut/Undub Patch
Nintendo 3DS

This patch aims to restore the cut content from the localized releases of Yu-Gi-Oh! ZEXAL World Duel Carnival by fully translating the original Japanese release into English. In other words, the patch requires the Japanese version of the game, known as Yu-Gi-Oh! ZEXAL Clash! Duel Carnival!.

All 41 character stories are playable in this version, as opposed to only 12 in the localized releases.

The tools used to edit the game files have also been made available on GitHub:

Emulators as well as real (homebrew-enabled) hardware are both supported through LayeredFS game patching.

When playing on console, make sure you're running Luma3DS CFW and follow any of these guides:
https://wiki.hacks.guide/wiki/3DS:Game_modification#Patching_using_LayeredFS
https://gist.github.com/PixelSergey/5dbb4a9b90d290736353fa58e4fcbb42#enabling-luma-layeredfs-game-patching

Or in short, copy the 00040000000F6C00 folder to /luma/titles/ on your SD card and enable Game Patching in the Luma configuration menu (accessible by holding Select while booting the console).

For emulators, open the emulator folder (there should be a menu entry in the emulator that directly takes you there). Copy the 00040000000F6C00 folder to /load/mods/ (you can just create the folders yourself if they don't exist yet).
