Goodwill find from Nintendo

[Keys]

Found a Japanese game diskette for use in the Nintendo Famicom external disk 
drive unit.  I could only find one disk in a clear carrying case.  The game 
is called ZANAC and from the pic's looks like a aircraft shoot-up game. 
Also at another thrift today I found 4 game cartridges for the Super 
Famicom.  I'm still looking for a power supply for the Super Famicom console 
I got from this same thrift last year.
