Hello there, I've been looking for a way to make a sprite swap mod for a visual novel published by Prototype for the Switch, called Fatal Twelve. The game uses .PAK files similar to other games published by Prototype.

I am having trouble extracting .pak and .dat files using the program. I am trying to figure out if the OpCode has something to do with it. I can upload any files for testing. If you have the time and are willing, support for extracting/repacking files for this game is appreciated. Thank you!

Here's the error I'm getting when trying to extract a CHARCG.PAK

Unhandled exception. System.IO.DirectoryNotFoundException: Could not find a part of the path 'C:\Users\[username]\Downloads\LucaSystemTool_release\LucaSystemTool\CHARCG_unpacked\aln_ban_nor_clo'.

UPDATE: My bad, I was using the wrong command. After using the export (was using import...), I now have extracted files. After looking at it in text editor, I can figure out they are CZ3, and exported them to png with the tool. However, some of the files are a little broken and will give me incomplete image data. How to fix?

From FONT.PAK, there are some files that I think will be able to do this. One is info52, and the others are the font bitmaps (明朝52 is included as an example), with 52 being the font size used for the in-game text.

I was able to export some files from info52 using 'info' as the file type (info52_, info52_dicStr_sort2.txt, info52_string_sort_utf-8.txt), and of these, I believe info52_dicStr_sort2.txt will let me edit the width of the characters when pulled from the font bitmap.

I was able to export the font bitmap 明朝52.png from 明朝52 using cz1 as the filetype. When using 'info' as the file type, I was able to export other files (明朝52_, 明朝52_dicStr_sort2.txt, 明朝52_string_sort_utf-8.txt), but I don't believe editing them is necessary.

My question is, if I edit info52_dicStr_sort2.txt from info52, and 明朝52.png from 明朝52, how do I import them back into the main files (info52 and 明朝52)? Let me know if I need to provide any more information or if any of my assumptions were incorrect. All of the files I've referenced are in the attached zip.

flowers_shiki_font_edit.zip

One last question that I'm sure won't have an answer: Is there a way to decrease the line spacing in the game's text box, and add a fourth line?

I don't know why, but some PNGs are not accepted by the game when converted to CZ0. When I looked at the file header and compared them to the existing one, I saw that they are different, here is an example in the picture.

When I copy the file header from the old file into the new one, the game accepts it and shows it.

Hello, what is the right command to repack the PAK archives?
When I try this kind of command: LucaSystemTools -t pak -m import -f wrk -o rdy pops up a bunch of errors.

D:\wrk\LucaSystemTool>LucaSystemTools -t pak -m import -f wrk -o rdy

Using a bunch lb_en

I am confused by the error Could not find a part of the path 'D:\wrk\LucaSystemTool\wrk\SCRIPT_unpacked\SEEN0513'.
There is no such folder SCRIPT_unpacked but SCRIPT .PAK _unpacked

当我试着使用命令 LucaSystemTools -t pak -m import -f SCRIPT.PAK_unpacked -o SCRIPT 打包LBEN的脚本文件时，出现以下错误：

打包别的目录不会报错，但也不能正确打包。是使用的命令不正确吗？

Hello!

First of all, I'm so glad to see work being done on LUCASystem engine. Your efforts seem quite amazing.

I wanted to ask whether supporting LBEE on PC is possible. I've tried out your tool on some of the files and it was a success, at least on image files. I could extract the font info files and the font images themselves.
I also tried to extract SCRIPT.PAK to get into the script files, and while it successfully gave me the raw files, I don't know where/how to find necessary opcodes for LB's script files to extract them in a "readable" and editable sense. I tried out some of the prebuilt OPCODES you guys have given with the files but they didn't work.
Can you help me with LBEE's files (especially to edit the font files and the script)? I wanted to translate this game to Turkish and it'd be a great help if you could help me. I can provide the necessary files if you're up for the task. Thank you so much beforehand and keep up the great work!

This kind of PAK can be found in Summer Pockets Reflection Blue on Switch.
PARTS2.zip

This is a patch to PARTS.PAK

It has the same files registered in header as in PARTS, but only files that are changed are actually packed while all other files are nulled in offset-size table (+entries in additional tables if necessary)

this is not an error related to not existing folder since this folder is created before crash. It works correctly for standard PAK files, but not for this type.

Solution: ignore all files with size nulled
