Translating CVMS engine without repacking or changing directory (クナド国記)

[Sisulizer]

Here is another guide how to hack CMVS engine .pb3 and .ps3, tested on Amatsutsumi(English), Seishun Fragile, Kunado Kokuki. I haven't tested on older format like .ps2 and .pb2 so I can't guarantee, but it might work who knows?

Tool requirement:

• _ Ps3 extract/insert tool (need python 3.x, also the line break should be \n)
• _ CmvsFileHook (need visual studio to build)
• _ GARbro (for extracting .ps3 and converting .pb3 to .png)
• _ xdb64
• _ CFF explorer (or different tool to inject the dll)

* The hook will help the engine jump to decryption algorithm (xor and decompress), that's why you just need to rename edited .png to .pb3 and put unencrypted ps3 in a folder which the hook preference to.

* The process is kinda complicated so I recorded a video how to do step by step here: Link

This is the final result:

Kunado Kokuki:

  Reveal hidden contents

  Reveal hidden contents

Amatsutsumi (Eng): (Because GARbro didn't work on this version so I use different tool to dump to bmp that explains why the image is not transparent)

  Reveal hidden contents

Seishun Fragile:

  Reveal hidden contents

CmvsFileHook does not currently exist...
If it does exist, you should update the guide, because the one currently available on github is not clear where to put the entry points.
