Thank you my man, been looking for hours to find one that workI'm going to leave here a WolfRPG extractor that I've found sometimes works when other ones don't. I think it has something to do with the version of WolfRPG that made the .wolf file, but I don't know any of the details at all.
I attached the entire archive as I found it, but the only file you should need is touhouSE.exe. Run that, set the file type to "all files" and then select the .wolf file you want to try to extract. I don't know what the other .exes do, and I don't know what game this was originally intended to unpack.
No guarantees of fitness or appropriateness for any purpose, and I can't really help out with it since it's just some tool I found on the internet.
