I downloaded a video that came from the Japan region, and I'm using Luma 8.1, but when I tried to load it, I got ERROR_MESSAGE_LOAD, any way I can fix this?
But locale switcher workedLuma Locale Switcher won't help.
So, go to GodMode9, enter sysNAND SD > title > 00040000 > TID Low (for that video app) > *.app > Mount as NCCH image/drive
(Check its Title ID with FBI)
Go to romfs folder and Copy "lang" folder to SD card,
Put in sdmc:\luma\titles\<TitleID>\romfs,
Inside lang folder, rename JP_Japanese to EU_English or US_English
(Do that on PC as it's easier)
Reboot 3DS and hold Select to open up Luma config, Enable game patching, save then you're done.
That's weird. It didn't work for me :/But locale switcher worked
