How to translate CMVS Engine games (PurpleSoftware)

[orangesunshine 1]

It was difficult to translate CMVS Engine games as there was no way to repack the files to CPZ. But it was found that the games work without packing to CPZ. You can try the following way.

Example: Mirai Nostalgia - H Scene Trial Edition

Editing scripts:

1. Unpack "data/pack/script.cpz" using arc_conv and move "code" folder into "data" folder

2.  Dump "data/code/snzh00.ps2" using Ps2TextDumper.exe and edit snzh00.ps2.txt (Save in UTF-8 without BOM)

3. Repack snzh00.ps2 using PurplePS3Packer.exe

4. Edit cmvs.cfg to change fonts

Editing images:

CMVS Engine can read PNG (No need to convert to PB3)

1. Unpack "data/pack/chip.cpz" using arc_conv and move "chip" folder into "data" folder

arc_conv -f cpz5 -c 0 chip.cpz

2. Convert PB3 to BMP using Pb3Decoder.exe

3. After editing the image, save it in PNG and rename the file extension from png to pb3

Editing start.ps2:

Settings required to read files unpacked from CPZ

1. Dump "data/pack/start.ps2" using Ps2TextDumper.exe and edit start.ps2.txt (Save in UTF-8 without BOM)

[0x0000155d]data\pack\script.cpz
;[0x0000155d]data\code\
...
[0x00001597]data\pack\chip.cpz
;[0x00001597]data\chip\

2. Repack start.ps2 using PurplePS3Packer.exe

Issues:

• Backlog is not displayed correctly.
  ->Using the latest executables for other games (e.g. Amatsutsumi-r64745) might improve it. In this case, rename "start.ps2" to "start.ps3", copy "main.ps2" and rename it to "main.ps3"

I confirmed that it works the same way in other games (Hapymaher, Chrono Clock, Amatsutsumi).

Hello there, sorry i'm kinda new to these things so i never use the .exe you use here except the arc_conv. I did try some searching to it but it seems i have to do the compiling myself. But the thing is, it seems i have to install vs2013 first to compile it as I'm currently using vs2019. Would you be so kind to share the .exe file you compiled? As it would save me the trouble to install 2 different vs in my low-end laptop, seeing just having one of them is enough to make my laptop screaming in agony.

 

I would still try to install vs2013 to see if my laptop can handle both though. Thanks in advance.

EDIT:
Silly me, it seems I can compile it just fine with vs2019. Just have to change the platform toolset of the project. Currently trying to mess with Amatsutsumi and hey it's working so thanks for the tips

EDIT2:
For anyone who just don't want the extra effort to convert .pb3 to .bmp one by one, just try to run this on your cmd:
for /r %i in (*.pb3) do Pb3Decoder.exe "%i"

I confirmed that it works the same way in other games (Hapymaher, Chrono Clock, Amatsutsumi).

You can do the same using SRL and GARbro. GARbro provides the ability to extract .cpz archives and .pb2/.pb3 images through UI, while SRL provides string replacements(editing scripts), It has auto install for CMVS engine, so it should be able to cover every CMVS game. imo it's a lot more convenient than having to use cmd. I also cooked up a simple piece of code which renames images from .png to .pb3 and vice versa, which you can download here(includes both the executable and source code).

If you want a more detailed guide on how to do it with this approach, you can find it here

Well, you can simple batch rename extension with this command on cmd: ren *.pb3 *.png, also same with from png to pb3: ren *.png *.pb3

And I made a little change to the ps3dumper to make sure it copies all the text to the second line (this need for inserting the text). Link

Just putting an alternative out there, since the method shown here does not work for me, loading freezes up on intproc.ps3 and never unfreezes, making the vn unplayable with the extracted scripts(perhaps I'm doing something wrong, however, as of now I've had little luck with it)

[Sisulizer 4]

Need to change also in cmvs.cfg

 

Also you can't use GARbro to extract since it will decrypt the scripts and that method only work when every .ps3 is extracted but still encrypted like this

I also found this on github

Thanks, I'll try that

GARbro can't decompile the ps3s

Sooo, changing the script init path changed the directory in which it looked for the start.ps3 script(rather than changing from where the cpz files are loaded from), which means moving start.ps3 into said directory, which would not coexist with the start.ps3 in the archive. as for extracting the archive itself, I did try out a few extractors that aren't GARbro, primarily this and this, all of which crashed when I tried extracting any .cpz archive

That's what I'm afraid about, there's also this tool, but the it's only work fir extracting specific games, like cpz7unpack work for aoitori only

This one I had to translate from chinese a bit, regardless, both cpz6 and cpz7 state it as an unsupported header. I've tried all the tools on both hapymaher and hapymaher fd, outcome is the same.

If only somebody can mode GARbro to extract without decyption...

@Grayscale Read this , seems like this is how you hook to make it read without encrypt and repack the files.

You can use CFF to inject the dll
