The region value in the
locale.txt isn't set to the region of the 3DS firmware but what is that game's retail region.
00040000
001BFB00 is the EUR version of
Metroid: Samus Returns.
00040000
001BB200 is the USA version of
Metroid: Samus Returns.
If you were to install the USA version of that game on your 3DS system running on Japanese firmware
11.13.0-45J, you would want the locale text like this:
- sdmc:/luma/titles/00040000001BB200/locale.txt
-
00040000
001BFC00 is the JPN version of
Metroid: Samus Returns (メトロイド サムスリターンズ).
If I were to install the JPN version of the game on my USA n3DSXL running North American firmware
11.13.0-45U, I would want the locale text like this:
- sdmc:/luma/titles/00040000001BFC00/locale.txt
-
Likewise, someone with a native EUR n2DSXL running European firmware
11.13.0-45E would also want the locale text for
Metroid: Samus Returns (JPN) exactly the same way.
- sdmc:/luma/titles/00040000001BFC00/locale.txt

A person in Korea with a Korean n3DSXL running Korean firmware
11.13.0-45K who wants to play the EUR version of that game? Yup, it would be like this:
- sdmc:/luma/titles/00040000001BFB00/locale.txt
-
- Instead of EN, this person wants to play it in FR for French language.
