I made some patches for MHX and MHXX that allow you to use the normal in game "Download" section to install DLC quests even if your system is banned. The patch will break multiplayer online play, so if your system isn't banned I don't recommend using it. The source code can be found here: https://github.com/svanheulen/misc_mh_patches I've attached a ZIP containing the compiled IPS files. Just extract it to the root of your SD card and make sure to select "Enable game patching" in the Luma3DS settings. Also you'll need to have the newest game update installed.
