Hacking ROM Hack Translation QUESTION - mod works on Ryujinx but not on Switch

[Bembee]

Hello,

So, I would like to translate a game to my language (actually it's a common thing in my country).
The game is Kathy Rain: Director's Cut. I successfully translate a line. When I copy the modified file to the corresponded romfs folder, on Ryujinx it's works well, but on real device (FW16.0.3 A1.5.4) it's said, "The software was closed because an error occurred."

Any advice?
BTW other game with modified romfs works well.

(works with Ryujinx) (NOT works on Real Switch)
