Hi snaaake....
I hacked a couple of those madcatz pads....
the smaller size one (the blue one) in my opinion is easier to hack... (after the hack, everything is still working....)
the larger one is harder to hack....
(I'm able to hack it but a couple of buttons on the pad is screwed....) which means I can ONLY use it as a hack....

sorry.... I'm stupid enough not to take any pics inside....
but since I've cable tied everything and its working fine... if not needed, I would not want to open it just to take pics....
ps: for the hack, I use those ribben cables to solder to the circuit board.... and then connect the ribbon cables to cat5 cables... (cat5 cable is too thick to solder directly on to the pad....)
let me know if you want more details...
ps: I've opened a MSFT original xbox pad....
from what I see... those are harder to hack than the madcatz....
and shoulder buttons...... the madcatz shoulder buttons has 3 wires... (cos its analog...) but you can just use 2 and it'll act like its pressed all the way.... (I believe its the middle one with one of the other one... you'll just have to try it out...)
