That's strange, I'm pretty sure I've seen ipdb links on Zen's forums before.
The sound card thing is interesting. Are you running two sets of speakers or something? How does that work?
I'm not familiar with the LED-wiz other than that it exists. I assume it's usually driven by the ROMs directly? I doubt Zen has any events for that kind of stuff coded in. Maybe you could re-use the rumble commands that it uses on Xbox/PS3, but I'm not sure when they fire. It probably rumbles on nudge, which you wouldn't want. Doesn't hurt to put it on the list if they want to get crazy.
If you can provide a bit more detail I'll add it to that thread. They probably don't know about all this custom stuff that is used with VP the way you guys do.
Sorry, I completely missed your post. Thanks for bumping mine on the Zen forums.
Support for two sound cards is a function that is available for VPM tables. It's easy to set it up, you can select a different sound device in the VP audio options and let vPinmame send it's output to the default device.
Many cab builders using the function send their VP output to a playfield monitor connected by hdmi, this way you don't even need a second sound card in your system.
I an a real nutter and added a second 2.1 sound system to my build. The ROM/backbox subwoofer is set to humane levels, the cabinet sound system's subwoofer is set to oomph.
It gives an more realistic experience since the physic sounds come from the backbox and its also - force feedback. If a bumper fires you know, even without contactors.
Supporting multiple sound cards might be possible to implement without too much hassle as you can already select different volume levels for music, effects and physics. For settings, this doesn't need to be fancy. A registry value or xml file would do the job.
My LED-Wiz isn't build in yet, so it's an area I don't have much experience yet.LED-Wiz is mainly it's ROM driven, but you can also trigger events in a script or in a VP original.
If you take a look at the discussion thread of VP originals like Scarface (my recommendation) you usually find a replacement script with LED-wiz support build in.
For FP, LED-Wiz support has been hacked in with DMD support. As with VP, it's a thing I have yet to try.
