I found a awesome bakin extractor

After several months. I've found an awesome extractor by a clever engineer: Bakin Extractor

• How to use：

python unpack.py rbpack_path output_directory

BakinUnpack

A repo for researching how to unpack games made in rpg develop bakin.

Why am I doing this?

RPG Developer Bakin is a new game makeing engine.

Apearly there is nothing on the internet to show how to unpack game file of bakin games.

I wondered how bakin packed game files and make its own struct, so I started to research their encoding and game files.

How to start?

I know little about bakin. So I googled it and asked some of my friends who also know little about bakin.

All I got is that bakin is a new version of SGB, also known as Smile Game Builder.

There is less bakin discussion on internet. But there is more discussion about SGB.

This section is based on a tweet from x. Also some of my inference. SGB uses a special file format called .sgbpack. And it has a certain pattern in its encoding:

• In the early edition of SGB using zip to pack its game file.
  • But it changed the file header from zip: 50 4B 03 04 14 00 00 00 to its own header: 59 55 4B 41 52 50 4B 47 (YUKARPKG)
• But soon official changes were made to the method of encoding:
  • 53 47 42 44 41 54 00 01 (SGBDAT)
  • Nobody knows how to deal with it.
  • And there is a high chance that Bakin still uses this encoding.

In bakin I assume it uses .rbpack to pack game files.

• I found that the header is 42 4b 4e 50 41 4b (BKNPAK).

temp file

I found out that bakin will create temp files during games at the windows temp path:

• C:\Users\{username}\AppData\Local\Temp\bakin_engine_tmp

There are many .rbr files. Still have no clue how to deal with it.
