Hacking Homebrew Translation Extracting script files from English RomFS to create English LayeredFS patch for Japanese cartridges

[varjak]

i'm expecting a few Japanese 3DS game cartridges for some games i have installed on my system in English. i have another 3DS system i would like to play these games on, hence the need for the cartridges to carry over my progress.

i was wondering if it would be possible to extract the English script files from the RomFS of my installed titles and create a LayeredFS patch to run the Japanese games in English.
if so, what files should i be looking for in the RomFS dump?

the games in question are Persona Q, Persona Q2 and Shin Megami Tensei IV

i did eventually figure this out.
i extracted the romfs folder of an English CIA file of SMT IV and was able to get the Japanese cartridge translated using Luma's LayeredFS.
