Appreciate you doing all of that. I think AV3 might be the answer here; that's pretty much the only thing I haven't tried yet.OK, I aim to be helpful! Here is Mr. Driller G working with HAS 4.0 and OSSC. HAS is using AV3 with the 8pin din to the OSSC via VGA adapter (the same settings for Taito F3). Note that these are NOT optimal settings, just a quick get it locked for you to see it works. I have to dial everything back in when I get back home in two weeks, but I'm waiting to update the OSSC FW, which erases all the settings anyway.Actually, that would be super helpful.Haven't had much time to take a look at it, but I remembered that I didn't fiddle with the volume knob at all when I connected headphones to the 3.5mm jack on the HAS... tried that, and -- sound! Ok, so the board is fine.My Mr. D 2 and Mr. D G PCBs both work great with the HAS and an OSSC. Once I get dug out a bit, I'll post the settings if that helps and no one has done it yet.This really doesn't tell much, because the HAS settings could have changed during shipping or during case assembly, it's been almost two years?When you say you don't get audio, have you also tried to plug in the headphones or speakers to the HAS' 3.5mm jack output? If not, please do it, wait a moment for the attract mode sounds (unless it's disabled, then add coins instead).I used to own a Mr Driller 2 PCB and also know people who own it and it works just fine, however not sure if it's compatible with the OSSC (it should be, though - try changing H-PLL pre and post coast settings).I think the HAS 3.1 is just using the default settings, other than the controller mappings that I set. It's outputting via SCART to the OSSC, and I've tried plugging headphones into the 3.5mm jack on the HAS, but I'm still not getting any audio going that route, either. The OSSC is set to Line5x mode; haven't tried switching to line2x or anything a little more lenient. The weird thing is that there's no audio or video, though - I could understand the OSSC having video issues but still outputting sound... but nothing? Just kinda weird. The board was working fine before the seller sent it, and it was well-packed... so that, combined with the fact that the board is getting power has me pretty confused as to what's happening.
All other JAMMA boards I have work fine with these settings. Cave stuff, CPS-2 stuff, ZN-2 stuff, etc.
edit: The most important question that I should have asked earlier - does the OSSC lock the signal (the OSSC's LCD screen should display the refresh rate of the signal)? If it does, but you don't see anything on the screen, then it's a problem with your TV set.
As for the OSSC, all it's telling me is "NO SYNC". I'll tinker with it a bit this weekend.

I haven't tried fiddling with the 240p/480i setting on the board either, but I know Mr. Driller 2 gives you the option. Wouldn't be surprised it the fix was as simple as that. I've got the manual scan, so maybe that's enough to navigate the service menu.
