I am a member on Pachitalk.com a forum about Japanese Pachinko and Pachislo and really dang near anything else actually.
I offered to the members there the service of the CC. I directed them to the free demo and offered to carve their creations. (pending operators review of course)
One creative member submitted these. I had to re import the art after removing the background in Adobe photo shop. Panel one is how I received the mpc and panel 2 edited is the other one after re-importing the artwork. I had trouble seeing the preview after removing the background but they imported OK.
