Yeah it seems to be stalling suddenly.  Try the direct link.

Not an original Front Line controler solution tho, right?

That rings a bell, what was that controller all about? Something to do with changing the rotation based on the joystick direction?   I came up with an add on logic circuit to do something like that, can't remember if it had bugs, there was something left potentially unresolved about it.  I can't remember what it was supposed to do but I'm sure I have it kicking around

TexasMAME - original Frontline controller works fine in MAME (AFAIK).  If you want to play it with a mech rotary, you need to build this circuit: http://ca.geocities.com/druins22@rogers.com/ls30/ls30exp.html

I was just about to post the link.  I found the files and added them to the site.

Apparently the "glitch" i recalled from the past was in a modification I tried to do to only momentarily do a keypress instead of the original circuit that holds the joystick down at all times. 

It's not a big deal and can be figured out if desired.  After a quick look at the modification I did to try making that circuit's outputs momentary,  maybe the glitch is in the fact that I'm using the inhibit pin of the counter chip with the same signal source that tells the counter to increment or decrement, so there is a "race condition" where I'm trying to simultaneously count while telling the chip it's allowed to count - if I'm feeding both control signals to the counter at the same time, who's to say the chip will be enabled in time to do the counting that I'm trying to do at exactly the same time.   

A little resistor/capacitor delay on the count up/count down pins may work so the inhibit pin is instantly addressed and then some short time later the count control arrives.

THat's assuming that IS the problem causing the glitch.  Either way that aspect of the design should be fixed.

I only did it with those chips so anyone could build it.  In a real project I'd just Atmel it and have no problems.

Tiger and Druin,

Thanx for the input.  I checked out that link and got dizzy.   :dizzy:  That's probably beyond me.

I do intend on getting one of the interfaces at some point, tho, since I do dig Ikari.

Guess it'll be an 8 way/top fire stick when the time comes for me!  :)

I wonder if a PC software solution is feasible - some sort of application that would monitor keystrokes coming in and if it sees a certain thing, generate its own simulated keystrokes to control the extra MAME inputs.
