BGI/Ethornell .arc rebuild

A python script made to fix the annoying amount of files when making a translation patch for a BGI/Ethornell Visual Novel.

What is this?/What does it do?

This is a python script that takes all the BGI/Ethornell files in a directory to repack a .arc file.

This is now part of BGI/Ethornell Tools, a collection of tools using Python for the BGI/Ethornell Engine. That includes:

• Extraction and rebuilding of .arc files
• Decompression and compression of DSC (extensionless) files.

Useful information

• Most dialog scripts are almost always stored in data015x0.arc. (data01500.arc, data01510.arc, data01520.arc and so on)

• Sometimes, menu images and CGs you might want to edit are stored in data025x0.arc.

• I strongly recommend you use crskycode's fork of GARbro to unpack the .arc files as well as marcussacana's SacanaWrapper with the plugin for BGI files to work with the scenario scripts and make translation easier.
