After playing around for a while, we discovered that you can crash Garfield Kart with a savegame packed with random data (in this case, a *hax payload ). It crashes to the home menu with the "An error has occurred, please restart the system." error. While using NTR, it'll crash with the black screen. System: A9LH, Luma o3DS 11.0 with 10.2 firmware.bin. Link to the save file: https://mega.nz/#!uJ4HwRDB!1uzm9I7x0SXxTlZixJaMGl8YiH9l_yZZpHYkdO2N33c To cause the game to crash, attempt to start a race.
