Summary	01020: taito_z.c, taito_f3.c. topspeed.c. sshangha.c: List of drivers which need PORT_IMPULSE.
Description	This is a growing list of drivers which need PORT_IMPULSE (previously PORT_BIT_IMPULSE). (taito_f3.c) The coin mechs uses a trick to prevent illegal coins. This may be "fixed" by using PORT_IMPULSE at 10 frames per press for the coin bits. (pgm.c) This driver requires PORT_IMPULSE on the coin bits as well that the game doesn't report coin presses at about 20+ frames. (taito_z.c) (topspeed.c) (sshangha.c)

There are some other weird cases too, see the hackery needed to get coins working in FunCube, it expects the coin to pass between 2 sensors within a certain timeframe in order to register as valid, thus 2 input bits need to be triggered with an appropriate timing.
No.04088 etabeta Developer Mar 27, 2009, 16:03	ok, thanks for the feedback. then I leave this open and confirmed, simply updating PORT_BIT_IMPULSE -> PORT_IMPULSE
