I had a hard time getting some more specific info on my problem, but here's the deal.

There's a problem with Lemmings 3D that creates driver error messages in the game's startup procedure, and I know this has come up before.

Now, it seems to be working in the official and current Dosbox 0.74, but I found a problem on the SVN builds. Unfortunately, I didn't have access to the pure Dosbox SVN builds because the older ones seem to have disappeared off the face of the earth entirely, but using the ykhwong Dosbox builds which claimed to be based on r3659, r3660, and r3661, I found a spot where the error is probably happening in straight Dosbox builds as well. I've noticed the error in the most recent Dosbox SVN build and the earliest one i could find available for download, r3752.

r3661 is where I know it no longer works, I'm not sure if the other one I tested was r3659 or r3660 since there was some overlap in the changelog of that build for some reason... But it worked in that one, so there you have it. Something changed somewhere along the line and it conflicts with the game. Knowing what it was is pretty important to getting this game working with sound again, not to mention finding potential workarounds.

A brief look at the svn changelog suggests r3658 could also be suspect, but it doesn't match up with what I've tried already.

Just thought I'd post it here since it seems to be a somewhat important issue for game compatibility that should be resolved before 0.75 becomes a thing. Unfortunately, I don't also have the time to set myself up to investigate this any further, I'm spreading myself thin as it is and the least I could do is open up a few versions of Dosbox under the same configuration to test a game.
