Need help unpacking .pac archive of ゴリマッチョとブルマレッスン / Gorimaccho to Bloomers Lesson

I wanted to open up this glorified video player's .pac file as there's some scenes (like a titjob scene) that aren't included with the standalone video the app comes with, but from what I've been reading online, this format is usually a custom archive that would need specialized tools to unpack. I've tried running the app on a sandbox but it doesn't appear to be extracting and dumping videos into the Temp folder in "AppData\Local\" so that's another method down. My PC is kinda ass so I can't really do screen recordings either, and I'd suspect there would be some quality loss if I go by this method. I've taken a look at the archive through a hex editor and I found multiple instances of directories and video files (.avi) stored inside it. Does anyone know of any way to pry this thing wide open?

Hello, it seems arc_unpacker can deal with those files (not sure tho) and I could only find this github issue so try this tool: https://github.com/vn-tools/arc_unpacker/issues/59

I dunno why, but it looks like this game's decoder doesn't exist in this current build anymore, despite the supported games list clearly mentioning it. It's not on the decoder list, but I can't find a mention as to why it's gone.

Oh wait, I just realized the pre-built stable releases never got to adding the Almond Collective decoders and that I have to build the exe from scratch to gain access.

Man, I really can't be assed to do that, can someone build the program for me? Can't seem to find a nightly build in the wild, and with the project being archived for 3 years now I can't really expect to get some help from the developers.
