|Sony Playstation: DoDonPachi
Released a year after the Saturn game (on the 10th September 1998), this is often considered the best version (even though the PS1 wasn't as powerful as the Saturn). This title actually featured a slow-down button, mapped to R1. It's actually a cool concept though today it would be considered sacrilege!
In 2010, this PS1 game was issued digitally on Sony's Japanese PSN as a PSOne classic.
A Taikenban demo disk was also issued in Japan. This was a one-level sampler allowing you to fly as any colored ship.
