I have a pi2 with retropi 3.5 running great on an arcade machine setup i built. It has all the roms, it has 2 mame setups for vertical and horizontal, and 2 x-arcade setups. i spent a lot of time getting this just right. Now I would like to try this setup on a pi zero I just picked up . is ther a way to mod this pi2 image as is to run on a pi zero?
