Hey :-)

I am working on an USB interface for Nintendos NES/SNES Joaypads.
I figured out that the NES joypad uses a HD14021B shift register.
Thats easy to work with but I could not find anything about the one in 
the SNES joypad.

It is labled as
1. line: "TG9530H"
2. line: "V520B"
and the screen print on the pcb says "IC-520B-ONLY"

please see the attached picture

Can anyone of you tell me where I can find a datasheet for that IC?

TIA chris
