I'm trying to make a mintypi as cheap as possible and I am don't know what gpio pins to solder my homemade gamepad into as this is the first thing I have tried to make with a raspberry pi. Also is there anyway to make my own powerboost or something similar to it.

You can use pretty much any of the pins circled with green and then set the GPIO (BCM on that site) number (NOT THE PIN NUMBER) in your config file.
