Default Shōjo Kakumei Utena: Itsuka Kakumeisareru Monogatari​'s DGP?

I'm trying to extract the images from Shōjo Kakumei Utena: Itsuka Kakumeisareru Monogatari​, it's a Sega Saturn game from way back, based on the show Revolutionary Girl Utena.

The images are in DGP format as attached. I have no idea how to get these into a more accessible format. If anybody could help, that would be so amazing. Thank you all in advance.

Image files are in a LZSS compressed 16bpp RGB format - easy enough to write a conversion tool without needing to debug the game executable.

See attached file for conversion tool and BMP files of the provided images.

Oh wow, thank you so much. I really really appreciate it.

However, can you please provide some instructions on how to do a conversion?

Dragging a DGP on top of dgpconv.exe doesn't give me anything that I can see.

Thanks.

The tool is supposed to be run from the command-line and is not set up for drag-and-drop.

If you really want drag-and-drop, create a bat file with the following contents in the same directory:

Code:
@echo off
for %%f in (%*) do dgpconv.exe %%f %%~dpnf.BMP
Then create a shortcut to the bat file also in the same directory. Now you can drag-and-drop DGP files onto the shortcut (you can skip this step if you add the path where dgpconv resides to the PATH environment variable).

Ahh, silly me. I just realized that not all the images are in the DGP format. I've attached additional CHP files that I'm hoping are the character images.

If you could take a look at them, that would be yet more awesome on top of the awesome you're already giving. Thank you so much, you're making me very happy.

No problem. Same compression as the background images, but the bitmaps are indexed rather than 16-bit RGB.

Here's and updated version of dgpconv that handles the .CHP images as well. There is a lot of data in the headers that I have no clue about, but it seems to work fine with the 5 provided images at least. I went ahead and added drag-and-drop support to the exe as well, so you don't need to mess around with the bat files.

You're a hero, thank you so much. Now I can finally make VNs for one of my all time favorite animes. Whoot.
