Thanks Buzz, that worked perfect. Playing PoP on the keyboard works great but not so well with a controller. They have a fully working menu to save, load, settings, exit, etc. now. You can jump, duck, etc. no problem but for some reason the analog and d-pad does some weird things when trying to move. I'll post over there and see if they can address it.
On a side note I was looking at the Dreamcade that is taking pre-orders now. I am on the fence because really if they sold their interface you could install it on an Intel NUC (looks almost exactly the same) and have the same product. They do have about 16 years building full arcade cabs so their interface is streamlined and polished. They originally were going to make it look like a retro style Atari-ish case but the final product is just a micro PC. Anyway I was just trying to view some video of the actual interface and product working and it's crazy the number of videos talking of being "RetroPie killer?" "Better than a RetroPie?", "The next RetroPie?", on and on. All I can think is they [RetroPie] is doing it right! :)
