Trying to extract .bin files from Sound Novel 'Portable Machi - Unmei no Kosaten Tokubetsu Hen'

Hey guys. I'm trying to extract the .bin files for this game but having no luck.
For addtional context, it's a game from the developers of 428 Shibuya Scramble and Danganronpa.

I tried using the danganronpa.bms script to unpack the .bin files, however I'm having no luck. It doesn't result in an error, however it doesn't extract the files either.

I've attached an example of a .bin file they have, if anyone can try and figure it the problem that'd be great.

This doesn't look like proper archive. It consists only of 0x0 and 0xFF.
I guess only game code knows what is this as file on its own is a pure garbage.
