pac-man joystick with mame keyboard hack
jmbrissie:
i used ghostkey, keyjammin, and keyhook, with all 3 programs i got to keep the left arrow to remain on with the switches open and joystick centered. when i moved the joystick in circles, ghostkey would produce a 3 key sequence then would keep left displayed until i hit left again. i tried to reproduce the other key malfunctions in pac-man and could only get the right direction to not work (left key sticks or does not reset). so i will look at the left key wiring and maybe redo it.
thanks for all of the help,
jmbrissie

I second mapping the key matrix, or at least the keys you intend to use to check for conflicts. The keyboard I'm hacking is organized into 8 collums and 17 rows. With the arrow keys, shift, control, return, space, and a few other prefered keys all on seperate rows, I don't expect any conflicts using my prefered keys.
As a side note, an older keyboard I mapped, the one currently hooked to my computer, and every other one I've played games on, I've never noted a ghosting problem with arrow keys alone. I have seen ghosting problems between arrow and other keys.

I will second the notion that GHOSTING IS *NOT* THE ISSUE HERE.
The arrow keys are a find choice for a Pac-Man control panel. All it has is one joystick, a P1 start and a P2 start.
I would also guess at a keyboard buffer problem.
Go into the BIOS and check the Typematic Delay settings.

You can get behavior like that if you accidentally wire to the NC connection of a microswitch instead of the NO connection. But you say you're using leafswitches, so this doesn't apply to you. I only mention it for future readers with similar symptoms.
