wow, that looks deliciously easy to hack. how is the USB cable connection to the PCB? is it solid? the last pad I got from DX actually came apart there so I had to re-solder and hot glue it down.

Got mine today too. Can't wait to try this baby out. Got a bartop just sitting & waiting for it  ;D

Just a word of warning (based on looking at this picture). It will be super easy to solder to these dedicated solder points, and the fact that the shoulder buttons have three wires (not four) is good because it means they are not part of a matrix and can be chopped off if not required.

HOWEVER, that D-Pad looks like many others I have hacked and appears to be matrixed, NOT a common ground... which means it may give you a little bit more trouble (need to figure out which is the ground for up/left, and which is the ground for down/right, and which/whether either of those is the same ground for the buttons and select/start etc.

The one I originally linked to in this thread is definately one ground. Many aftermarket playstation2 controllers are common ground for everything except the select/start/analog button... but many 'super cheap' chinese controllers have matrixed (not common ground) d-pads, as this one appears to have.

Interesting to know.

I can vouch for the GGG pads having a common ground for everything. Been "testing" it out for a good few weeks. she plays SFII, KI, and everything else without a hitch!

It seems to me that the up/right have there ground as the little horizontal jumper, and the rest all have a common ground.  It doesn't seem to be a problem to connect both grounds (since the 2 grounds connecting doesn't make a button press) but I may be very wrong...


edit: actually it would cause a problem (both the left and right would have the same button press) but if you just don't use 2 of the buttons then the entire controller has a common ground, otherwise there are 2 grounds.
