Great pic, classic balls hard check point STG. I think it has to be a 1cc b/c if you die in stage 4 or 5, might as well start over due to losing power ups.
Visually, the card and CD are just about the same to me, it's the CD tunes that make it a "get" for me. I don't think I've ever seen any extra stage(s) but maybe this month I'll attempt to get good.
