LayeredFS can't check if file is broken, so if it was, then game would crash or translated lines would be broken.
So you have 3 options:
1. TitleID is wrong (probably not)
2. You have put files in wrong folder
3. Your modified files in real are not responsible for translation (f.e. dummy files)
Ok, that's good to know! Maybe i should try removing some files, and see if i can get the game to crash - this way i can at least confirm that it's working I'll try that tonight.
I have checked the title folder with Kip Select, and it does recognise "Dragon quest builder 2" (and it is enabled) so i'm very certain that the title ID is correct.
In regards of 2., i have copied the file structure I see when inspecting the romfs.istorage with XCI explorer, so i assume it's correct. Any idea on another method to check the file structure for the title folder?
Could it perhaps be that i need to add some stuff to exefs?
Thanks for the input!
