Am I the only one that understands how the PS3 controller goes back together???

Just reverse the way it came apart... not hard.

On my DS3, the R2 button was lose because the spring was broken so I decided to open an old sixaxis controler I had and take the spring from this one.

Opened both and replaced the broken spring closed both and they both work perfectly ( appart from the loose R2 button on the sixaxis obviously ). I didn't go as far as the D-PAD but just remember every step, remember what goes where and don't lose anything and as said above, be VERY delicate. You also have to be very patient because you will spend some time with it.

An other advice, once you put the control back together, don't screw it yet. Just hold it in your hand and push every buttons, if it doesn't feel right or if you cannot push some buttons then reopen it and see what's wrong. Don't close it completely until your controler feels as good as new.

The Left, and Down buttons click, and don't respond properly.  People mistake me for using an arcade stick all the time in MvC2.  I'm not as good as I could be, but, I'm good enough in Tekken 6.  Anyway... I'm thinking about putting up with the controller... Otherwise, I'll be limited to this off-brand PS2 controller, and won't be able to use 6 axis, or the XMB...  Unless I can massage the part back in place.

I dunno, maybe I'll just lift the front plate off, and fit the pad directly in place.  Maybe I'll even take apart the Dual Shock 2 just to refresh my memory... it doesn't work anyway.  I'm not going to do it until I'm actually in the mood, though.  Doing it when I don't feel like it would be asking for trouble.

Well make sure you remove the battery and don't cut yourself while doing it, as even a small battery can kill you if it there's an electrical path to your heart (for example a cut on your finger touching a metal contact... worse even if it's on two fingers on opposite hands).

It's a 3.7 V battery, it wouldn't even tickle him.

Wrong. A 3.7 V battery can generate enough current to kill you, IF the current flows through your blood (which is basically water thus highly conductive).

If it flows through the skin it's no problem of course.

Tekken is a completely different fighting mechanic than MVC2, which allows proper use of a controller to a much higher degree. 

no, dont take it apart! lol

Lipo batteries are NOT going to kill you through a cut. There are so many variables that would have to happen just for the slightest .00000001% possibility. How many batteries have you actually handled in your life that weren't AA or part of a camera? 

I build packs for MANY MANY applications, and not once have I ever EVER remotely even come close to shocking myself. I've had Lipo/Life packs blow on me, alkalines leak, but NEVER got a shock from anything. I've worked with NiCd, NiMh, LiPo, Alkaline, Life, etc. 

I take that back, stick a 9v battery on your tongue, that tickles. 

My Triangle button sorta jams or sticks now =/ I treated it like absolute crap so I should be glad it's such a tiny problem.
