Hanshin Tigers DS ripping help?

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?
