Off the bat, let me say this forum is fantastic. The amount of information in here is slightly overwhelming, but oh so encouraging.
I'm not sure this is the right subforum, but what the heck. I'm planning my first cab, and am a firm believer in trial and error. Do it once, and if it's terrible, do it again. and again, and again if necessary. Mistakes are just opportunities to earn scars and learn what not to do.
So far I'm looking at a starter pack of zippy 8 way joysticks, xinmo controller and buttons. It's going to run on a laptop thats a couple of years old I have lying around, and will use an old LCD monitor and computer speakers I no longer use.
I feel like I'm on the right track, but am willing to listen to more experienced voices if this is a recipe for disaster with no possibility of success.
