Item description:

supermysterychunkhax utilizes a savegame heap overflow in order to run *hax. To install such a savegame, an existing homebrew entrypoint such as browser hax, Smash Bros or Cubic Ninja is required.
To launch *hax, first make sure you download and extract the latest homebrew starter kit to the SD card.
To install the exploit to a Super Mystery Dungeon cartridge or digital download use the installer found here, extract it to your SD card and run it using the Homebrew Launcher. In the installer you will be prompted to select the appropriate version for the system and then the selected exploit version will be downloaded and installed.
Note that installing supermysterychunkhax will wipe any existing savegame data, and the original game will not be able to be used while supermysterychunkhax is installed. As such it is suggested that a savegame backup be made before installing
