How to modify romfs?

[notsu]

I have a game that uses .csv files for the script, which are located under romfs/script/scene.csv. I translated one of the CSV files near the start of the game but I'm not sure how I can replace the current file with it.

I'd suggest using Atmosphere's LayeredFS functionality. Basically a file override system where the game will read a custom file on the SD card instead of the one in the games data. Structure is rather simple /atmosphere/contents/(TITLEID)/romfs/

Remember to match the file/folder structure of the game's original RomFS though. So if you modified a file that is in a subfolder make that folder and put it in it.

That's the first thing I tried but it didn't do anything. To test if it would actually work, I slightly edited a CSV from the beginning of the game [changed one ハ to は], placed it as follows: atmosphere/contents/[TID]/romfs/[originalname].csv and rebooted my Switch before booting the game.

I'd also double check your titleID and make sure game updates arent messing it up. But here's a short tutorial as well. https://jeffvi.github.io/switch-guide/extras/game_modding.html

That's actually the guide I first went to for troubleshooting, lol. What I did seems to be correct. And my TID should be correct as it was copy pasted from EdiZon ovl with the game open. Also confirmed it with nswdb.

Only thing I could think of is the game may not be reading the reading from the exact file you think it is? Not sure past that.

I'm pretty sure it is, as I matched the entire scene's dialogue with the CSV before editing it. I also confirmed that none of the other CSVs contained the exact same lines.

Yeah can't say then. I'm not familiar with this game or engine so I can't confirm if the game has some weird loading function.
