Fixing broken timer on M82 DEMO UNIT

I recently acquired an M82 DEMO UNIT.

The timer for it appears to be stuck on 30 sec, so it'll auto-change game every 30th second. The switch on the unit was broken, as it clearly made no working connection. However, unplugging the cable for the switch still makes it auto-change game every 30th second (I guess this is the default state/config).

Does anyone know what the pin-out for the timer is? Which pins need to conect for it to evt. use 3 min, 6 min or 128min instead of the 30sec setting? The fact that it reboots like this at 30sec intervals can't come from any other potential issues, right? (It's always a fixed timer, so I'm pretty sure it's the 30 sec minimum setting).


Here's the unit itself (w/out case, that is)

This here is the switch (a reanrenaud RTA rotary switch like this one

Here's the connection point

 

Added pics to the OP.
Now, according to what I'm observing in GameTech's video, the brown wire (left) is the one that's to be cominbed with the others for different time settings (based on video: Green = 128m, Yellow = 6m, orange = 3m and red = 30s). The one seen in GameTech's video stays at 128m when the timer switch is not connected to the unit itself, but mine stays at 30s when the timer switch is detached (and is currently stuck at 30s too, it seems). Is this a PAL unit thing or is there something else that could trigger this -- could I just hard wire the right pins from the connector point and reach the desired result?

 

It has been awhile since I have watched Game-tech's videos on it, but didn't he and Kevtris replace the M82 ROM and disable the timer in addition to other things.



I am not sure if he disabled/enabled timer there or changed one of the time settings to be a selectable "timer off" or not, but perhaps you could contact him regarding a replacement ROM and go that route.

Congrats on the M82. It seems like a fun little (errr..."big") unit.

 

Yeah. Kevin did a replacement ROM for it that has some extra features (mailed him earlier tonight, hoping for a reply). While the additional features aren't that important to me, I'd love to get this thing up and running, in a slightly more playable state than these 30s auto-resets provide, before next weekend. Doubt shipping a new ROM from the US to EU would get here on time for that, though.

 

Ahh man. Yeah, that would need to be pretty quick. If Kevin is pretty open to the idea, he could always provide the ROM (code) to someone local to you (for burning) in order to speed up physical acquisition.

You may also want to offer to tip him for it as I don't think it is something he officially sells & he spent a good amount of time on it. You probably already thought of that - I just really appreciate the work he does.

 

Checked all the cables for the timer switch and made sure connections are actually made. Tried removing the entire motherboard et al from the device and it still refuses to acknowledge anything but a forced 30 sec reboot cycle. As I'm not really equipped to properly checked every little detail on this thing, I guess the only solution is to get ROM replaced on it with one that ignores the timer (or acts with a timer of its own)
