Actually, what it does is use the BIOS palette manipulation code instead of writing directly (and very quickly and incompatibly) to the VGA chipset.

Cool.

As long as it works! 

Have you tried the current CVS version of UQM, Mike? The Quasispace portal shows up for me when I load your save from the bug database, so using the CVS version might fix your problem.

Thanks for the suggestion, but it still didn't work. I did notice something though. It was a bit quiet in hyperspace while I was camping at the point where the portal would normally spawn. On the 17th, no portal appeared but a Slylandro suddenly appeared in hyperspace at that moment coming in from the edge of the little Hyperspace map. I waited another month but the same thing didn't happen. Maybe it's just a coincidence but it might be significant. 

How do you get the graphics to work right in DOSbox for SC2? I have graphics card set to 'auto' and the game keeps changing colours into some unreadable combinations.

Try running the game by typing this on the command line:

starcon2 /g:bios

This should get it to use the default BIOS colours instead of a dodgy colour palette. Alternitively, if you haven't already done so, try UQM.

See this thread for the answer.

As for the .ogg file being missing, this is just a music file. If one of these is missing I think it just plays the original .mod sound instead.

If it is the same problem (described jhere on the SCDB), there should be other symptoms. The most noticable one would be that no ships would ever show up in HyperSpace, even the Melnorme if you call for it.

This aspect of the game still functions as it should for me. I'm able to see all the graphics associated with another race in Hyperspace (blip on the radar, black hole following ship in Hyperspace) and I get pulled out of Hyperspace on contact just as I should.

Add this to the command line when launching:

-m pc

Done.

But since it doesn't seem to be happening to anyone else apart from the reporter of the bug, that suggests that the problem is probably on my end so a saved game of mine could work for everyone else.
