Reply to Arcade Mod

Okay so I know this post has been made before because I've used search however I haven't found a definitive "guide" thread to doing the arcade mod yourself.

1) What parts do I need to purchase? Exact button model numbers? Diodes?

2) Definitive measurement method for holes

3) soldering instructions

I know tons of you guys have done this mod yourselves so tell me how it's done
