@ST Dragon : parasol stars never existed as a coin op, this was confirmed by Mick West,
PS coder. He works from the pc engine version GFX, they downgraded them from 512 colors to 32.
The pc engine can throw more colors on screen than a regular amiga hence less colorfull GFX.
Taito themselves said there is no coin op of Parasol stars.
The game also exist on atari ST.
