Tools for Yeti/Regista/Cyberfront console games

[Nanashi3]

Hello everyone,

 

 

I hereby proudly present a modest set of tools which aim at pulling out text from console VNs published by Yeti/Regista/Cyberfront.

There was no identifiable name for the VN engine, and it is only one among many others Cyberfront etc. use.

 

Tested titles are:

• Cross + Channel PSP and X360
• Secret Game and its sequel Rebellion's PSP
• Kana Imouto PSP
• Hoshizora Planet PSP
• Ryuu-Koku PSP
• Konneko PSP
• Tamayura PSP
• Root Double X360

 

 

Those tools were written in Python 3 and may be freely used provided proper credit is given.

Since it is a dynamic scripting language, sourcecode is freely available.

 

 

 

You may download it from this Github repository:

https://github.com/mchubby/yetireg_tools

 

 

 

Hit "Download ZIP" to grab the whole directory.

 

 

 

 

How to use it:

 

0- Install Python 3 (whatever version)

 

 

1- Unzip archive contents. Edit all PS1 files to match your Python 3 path.

 

 

2- Extract sn.bin from your game media and copy it into the same folder. Give it a significant name, e.g. sg2psp-sn.bin

 

 

3- Open a Powershell prompt and change directory to the extract folder

 

 

4- Run _1-extpak.ps1 ( C:\Mydir PS> .\_1-extpak.ps1 )

It should generate a bunch of z__*.opcodescript files

 

 

5- Run _2-extjis.ps1 ( C:\Mydir PS> .\_2-extjis.ps1 )

For each opcodescript, a resource txt file may appear depending on whether strings were detected.

 

 

6-Optionally you may want to convert those txt files to po for importing them into a Weblate project for instance

 

 

You may also want to take a look at the presentation I created for installing Weblate on a cloud service: https://slid.es/mchubby/weblate-on-pythonanywhere

I had no time to retest the whole process again though >_<

 

 

Known Non-Bugs:

• The last item of each archive is not a game script. It certainly serves a purpose, but it does not matter as far as text extraction is concerned.

 

 

Known Bugs:

• Rebellion's SG script 002 won't be parsed correctly.. Not that it matters, it seems to be an orphan script.

 

 

 

 

TODO:

1. Decode root double PS3 (BLJM-61100) 's sn.sdat, but I cannot find the corresponding klicensee even after bruteforcing. help?
    
2. Figure out bitmap format of XTX graphics mode 1 and 2 
   asmodean's spc2bmp only supports 32bpp bitmaps (mode 0)
   only clue I have atm is http://tieba.baidu.com/p/2397878791  ; they have the same issue here http://tieba.baidu.com/p/2631815322

 

 

PS: @Ziddy, apologies for not answering PMs, I was horribly busy

Hey, that's cool. I've got some suggestions though. It's [probably] possible to use bitbucket for git hosting (I assume you need a private repo). Also, I find the following directory scheme more pleasant to work with:
