Mamehooker Ammo Counter Display

[oddeye45]

Hi all,

This is a question probably aimed at Howard Casto but I'll take advice from anybody that knows how really. I have some Aliens Extermination guns with the display counter on them. I know that there was a Terminator Salvation cabinet that had these guns (positional) installed on them rather than actual light guns and Mamehooker shows an output for ammo counters.

However, when I try to use the ammo counter output, one of two things happens. Either:
1.) The counter works but only scrolling from 9 to 1 and then looping back to 9
OR
2.) Both digits do the same as above but both digits show the same value

The code I am using is:
1.) ghd 1 &H04B4 &H6870 3 &h03:&h00:&h0%s%
2.) ghd 1 &H04B4 &H6870 3 &h03:&h0%s%:&h0%s%

Can anybody see what I would have to alter to get it to do what I want? I can see why it is doing what it does (in scenario 1 I am telling it to display zero as the first digit and in scenario 2 I am telling it to change both of the digits when the output changes to a zero or a one) but I have no idea as to how I would tell it to read the two-digit value of the ammo and output that.

Thanks in advance if anyone knows how to achieve this.
