Yes, thats aztarac.
Also, Its used in Mad Planets.
I only know this, because Ive been collecting underside control pics
for the project Ive been trying to put together.
This is yet another reason for such a project. To know where a controller came from, its history, its workings...ect. Even if its just for plain trivial knowledge.
Im pretty sure thats a really rare find. Suprised it went so low in cost.
Then again... there arnt many of those games arround Ill bet. But advertising it with those game titles, and posting to collector newsgroups, may yeild a higher resale.
