I felt like putting down everything that is known about PPADS and MvC2 frame skipping cycle down so i wrote 1 and a half articles explaining mvc2 frame cycle and 100% techniques.
Huge thanks to Art/Maj for letting me use a bunch of his info and helping me with the 100% technique.
Introduction to Programmable Controllers

Of course, this information is pretty much useless unless you have interest or have a program pad so yeah.
