So the Konami DDR games have an IO board for each player located inside the dance platform (often called the Pad IO or Stage IO). it looks like this:
These things are expensive (~$250 for a fully working one) and they like to die (I have a few dead ones and one partially working one).
The boards have 2 functions, 1 input from the dance pad, and 2 output for the dance pad lights.
There's not much to these and on my dead ones I've verified every last component as good except for that XILINX XC9536 chip.
So I'm curious if there is a dump of this chip available so that I could potentially make some replacements for my dead boards.
AFAIK this chip only serves 2 functions.
1. it acts like a 4-input OR gate for each pad arrow (4 sensors per arrow, so any one of the sensors tripping registers as a step for use in dance mode (this is routed directly to the joystick pins of the JAMMA connector)
2. It has some kind of communication with the system573 for use only in test mode, so that it can communicate explicitly which of the 16 sensors is being tripped (this is communicated through a separate I/O connector on the system 573). I think this also needs a "ready" signal from the 573 as when you disconnect this I/O connector from the 573 it will partially disable the dance platform outputs until you jump one of the pins on the connector to ground.
