New Idea Factory/Compile Heart Game File Extraction Need Help

[KirinaYuuki]

Hello,

Somewhere after 2018, Idea Factory/Compile Heart changed the encryption type of their game files for good, from .pac and .cl3 files to .dat files. Since .dat is a really ambiguous file type I tried every script available on the quickbms site related to .dat files but none of them worked. Can somebody help me with a new script to extract these game files? Here are some gdrive links to examples (these are from Dragon Star Varnir):

21.6MB one: https://drive.google.com/open?id=1VE7l_r4Z7MtOS2akIiL2TQSMVlYf4J2q
341MB one: https://drive.google.com/open?id=1n3gruLo0h_BxagCx8aUn-XKsLzALNBR3
1.25GB one: https://drive.google.com/open?id=1k-fM3t93JXbRvCrbLqfMhrSQv_jCDv2S

Thanks a ton! I want to be able to translate these games and extract the raw images in the files.
