Hacking ROM Hack [Help] Translating Yo-kai Sangokushi into Korean – What should I do after extracting RomFS?

[spidychoi]

Hi everyone.

I want to translate Yo-kai Sangokushi into Korean, but I'm completely new to game translation.

I've looked through various tutorials and posts, but I couldn't find anything that clearly explained what to do for this game.

So far, I managed to extract the RomFS from the CIA and I found a bunch of files, but now I'm stuck and don't really know what I should do next.

This is my first time doing a game translation, so any advice, tutorials, tools, or guidance on where to start would be greatly appreciated.

Here is what I have so far:

What should I do next to find and extract the game's text files?

Also, does anyone know what tools are normally used to extract/rebuild LINKDATA_A.BIN for this game?

Any help would be appreciated!

You wrote in your other post:

I found a tool on GitHub (since English and Korean patching processes are basically identical, right?), but sadly, it’s built on Python 2.7.

Why don't you provide a link to whatever tool you were looking at?

It is going to be very difficult to make any kind of patch if you have to make the tools from scratch.

(I think this type of thing is rare for most of the game but here it is)

Okay? That page includes clear instructions for extracting data from LINKDATA_A.BIN.

I think so maybe I should get python version manage thing to run? (Thabks for the reply)

I'm not sure you're trying to read the page? It says right there:

Download link (includes 64-bit Windows compiled executables): https://github.com/kuronosuFear/SangoKuro/releases/download/v1.2/SangoKuro.7z

I know but maybe I should use python version manage app so that I can run latest version and 2.7? If I should what should I use?

Why do you keep talking about Python? You don't need to do anything with Python! The .7z contains the .exe files! That's all you need!

If you unzip it you'll see python script folder. When I used this tool with ai it used the exe and try to use python script also

with ai

You don't need to use AI! Follow the instructions!
