ok so im pretty noob at controller mods and went to do my first one and found i have this new board
i want to add an a and b button..... where should i connect the grounds?
also can someone direct me to the correct vias to solder to so i can double check that i am using the correct ones for the positive?
any help would be awesome..... thanx
i are noob
Ground is ground, you can use any spot for that connection, TP2 and TP22 on the back side of the board are real good ones for that. As for the A and B vias to use, be VERY careful scraping them down and soldering the wire to them, if they get messed up it would be a real witch to fix that thing back up so it worked again.
Green is A, Red is B

EDIT: OK so I don't use the resistors... I just use the PNP Transistor wired to RT1 & RT2... The last connection on the PNP Transistor is then connected to a ground (common ground in my case) to create a button press and RT3 is not used at all. Is this all correct?
Also is there any particular PNP transistor I should get?
No, if you connect the Base of the Transistor to ground it'll be on all the time and a 10k or so Resistor should be used between the Base and Emitter leads to make sure it stays off when it's not used, and unless you leave the Triggers installed yes a 10k will still need to be installed there as well. You want the Base lead to be wired to whatever button you're going to press that ya want to be the Trigger, so when that button is pressed THEN the Base is connected to ground, are ya pickin up what I'm layin down? Any small signal type PNP Transistor will do, it's just being used as a switch.
