Hello, I am trying to extract the sprites and music from "Touhou Imperishable Night for Busy Person" by KasugaSoft. It has a data.xp3 file and a ksgdec.tpm. I have tried using Crass and it either extracts a warning text or just outputs "Crass Runtime Error.Access Violence.All Done.", I also tried using the command line, but that also gets stuck after extracting the warning text. I have also tried GARBro, arc-unpacker, xp3viewer, and Extractdata. The times I have managed to "extract" the files, everything is encrypted and will not open.
Any help with this would be greatly appreciated!
