>>40292198Install Luma if you haven't yet (guide here
>>>/vg/hbg/)
I don't remember if the Luma guide tells you to do this, so just in case: when you reach the Luma configuration menu (hold Select while the 3DS is turning on) make sure "Enable game patching" is enabled.
After that, your SD card should have a "luma" folder. Inside that folder, there should be a "titles" folder (create it if it's not there).
Inside the "titles" folder, create another folder called either "0004000000174400" (for the European version) or "0004000000174600" (for the American version). Inside this folder, create yet another folder called "RomFS", and inside that folder, one more folder called "script". And inside "script", another folder called "menu".
Put this file inside "menu".

When you're in a dungeon, press B to open the items menu, that will also zoom out the view. I'm sure there's a way to zoom out automatically, but I haven't found it yet since this was good enough for me.
