/***************************************************************************************** Speed Attack! (c) 1984 Seta Kikaku Corp. driver by Pierpaolo Prazzoli & Angelo Salese, based on early work by David Haywood TODO: - Video emulation requires a major conversion to the HD46505SP C.R.T. chip (MC6845 clone) - It's possible that there is only one coin chute and not two,needs a real board to know more about it. How to play: - A to D selects a card. - Turn takes one or more cards into your hand (depends on how many cards you putted on the stacks). - Left & right puts a card on one of the two stacks. Notes: - According to the text gfx rom, there are also a Taito and a KKK versions out there. ------------------------------------------------------------------------------------------ SPEED ATTACK!
