It works. For future reference for anyone who finds this thread: If you get errors about missing DLLs then the easiest solution is to compile it manually. Install Visual Studio tools and use a command like `cl.exe plt.cpp /std:c++latest` to generate the EXE. Drag the plt files onto the exe. The PLT files must be in the same directory as the exe and must be renamed to contain no strange characters.

While I do have some background in programming, I know very little about those technologies. I suppose it would be asking a lot to give a detailed description to a relative layperson like myself. Would it be possible for you to give the code for your application so I could take a look and compile it myself? I don't feel particularly safe running a random EXE.

You are a god, thank you. Access is denied to the drive folder, looks like it wasn't set to public access. If you could provide instructions on how you located the decryption algorithm or found the encryption key then I could try my hand at decoding other games.

I am trying to unpack JK Imouto https://vndb.org/v26382. Garbro opens the arc files but some of the animations are contained within PLT files that Garbro cannot open. If I extract the files using Garbro then the PLTs can be further extracted with Arc Unpacker using the decoder kaguya/pl10 but the resulting files are multicolored static noise. The existence of https://exhentai.org/s/e9f656b86f/1560836-11 implies that those files CAN be extracted and I just haven't found the right process. Does anyone know how? For each PLT file there is an ANM archive that appears to be empty. I have placed the files into a sharable folder.https://drive.google.com/drive/folders/1Kl_e5y0gUCmmJ1iWNP1-FCnFr2QK0JPd?usp=sharing Thank you.
