I tried that a few mn ago, i downloaded them from the hack nintedo site and unpacked to the root of sd card.
No issues with other games. I was able to play Xenoblade 3 dlc which released quite recently.
For some reason i got "Software closed because an error occurred" when i try to launch the game. Hekate, Atmosphere and Sigpatches are fully update. Any idea of what could be the problem ? :(
