Save editor Config and Script files

To download working Editor Config and Editor Script files, visit this repository

Check out our Wiki page for more information on how to build your own Editor Config and Editor Script files.

How to install

  1. Download the latest release from the GitHub release page.
  2. Unpack the downloaded zip file, put the files on your Nintendo Switch's SD card and let the folders merge.
  3. Use a free open source CFW like Atmosphère to launch the hbmenu and start EdiZon from there.
    1. If you want to use the cheat manager you absolutely have to use Atmosphère as only their cheat service is supported.
    2. For the best experience, open the /atmosphere/system_settings.ini file and change dmnt_cheats_enabled_by_default = u8!0x1 to dmnt_cheats_enabled_by_default = u8!0x0.

How to compile

  1. Clone the EdiZon repo to your computer using git clone https://github.com/WerWolv/EdiZon --recurse-submodules.
  2. Download and install devkitA64. It comes bundled with the devkitPro toolchain.
  3. Use the pacman package manager that comes with devkitPro to download and install libnx, the switch portlibs (switch-portlibs), the switch OpenGL libs (switch-glfw, switch-mesa and switch-glm).
  4. The rest of the compilation works using the make command. Type make application to build only EdiZon, make sysmodule to build only the companion sysmodule or just make to build everything.
  5. If you want to use the debug utilities built into the makefile, you also need python3 and lftp installed on your computer and sys-ftpd installed on your Switch.
