Re: Sega XY - free play revisited

Yes, this is very similar to how I've got free play set up on my 4-player
Eliminator. It's all about timing the pressing of the button so that it
represents a coin rolling over the switch. However, when you've got four
people trying to do this at the same time, and everytime someone mis-times it,
the CPU locks up temporarily, it's get's really annoying really fast.

On my upright, there doesn't seem to be that timing issue if you directly hook
up a credit button in place of the coin switch.

somebody might be interested in the "officially" supported free play method. It
looks like all they did was add an extra wire from each of the player start
buttons directly to the coin switch ON connections at connector P2. Player 1
to Switch 1 on, Player 2 to Switch 2 on. As you can tell from the text above,
it's pretty quirky to use, but it does work.
