The VG Resource

I recently stumbled upon some NPB-based game for the Hanshin Tigers, which runs on the Nintendo DS/DSlite. The only two models I'm trying to rip are the team's mascots To-Lucky (male) and Lucky (female).

But, the one problem is that all of the data is compiled into a .dat file, which is in a completely different format, and doesn't include a .cue file. Can someone please help me with this?

Bad news: Had a look at the .bin file, and it looks like there are custom compressed archives within it, and then good ol' NSBMD files within them. Being compressed makes it currently impossible to extract them, although you can see the magic words in there.
