Dredging up this topic, since I picked up an ArPiCade recently. Did you ever get WolfMAME working on a Pi? If so, were you able to get it to run and record an .inp also?
Hey buddy. Sorry for the late response - i've not been super active on DKF recently. I did end up getting WolfMAME to
run on the pi (I have a pi 3), although it took a lot of work and the end result was less than desirable (very very low framerate & intermittent crashing). I gave up after not being able to get a playable result.
I'm somewhat optimistic about the Pi4 as it's capable of a lot more processing power - but I don't have one on hand and I'm not sure I saved the work I did to get it working on my Pi. I ended up moving my Arpicade into my Lowboy after I picked up a DK 2-stack.
It might be worth the effort to reach out to Dee2er on the Arpicade forums if you haven't already! I'm also happy to help where I can if you have any specific questions. @fippi on twitch or @jackary on instagram are the best places to catch me ~
