Hah - yes well OK you need a USB cable to push payloads atm but if on 1.0.0 you can enter RCM thru software only without need to tamper with any pins/thin wires/shorting or anything.
That's the gist of this as well as the later instruction to document how to do it all from scratch on Windows only.
interesting. ok then this is the guide for me as i'm on 1.0. but i guess i still need a copy of puyo puyo to get into pegaswitch at least the first time.
