(My personal 2c worth) I would actually recommend starting with a very good book on the "C" programming language (to understand what the code does and also debugging and the "stack" concepts). ( I spent plenty of time in 8086 books, but although I could write simulators, could not understand why …

I recall trying to use Bochs for a disassembly project many years ago, and it turned out that the decoding was incorrect (I ended up coupling to Nasm to get the correct disassembly). So I would suggest that as a good reference.

You could also access the characters using chr(index); Returns a char/string(1) eg, Copy code to clipboard 1 printf( chr(219)+chr(219)+" Hello "+chr(219)+chr(219)); etc

Personally I have been building with (free) MinGW.. as WD stated though graphics is mostly 'outsourced' to libSDL, so the problem is likely in there. It might help to try a different version of SDL.DLL. (You may have conflicting versions in %windir% and Dosbox build)

Hmm.. Try set the swapfile to be a fixed size (Right+Ctrl on My Computer, properties/advanced/Settings/Advanced/Change .. something like min=max =512mb on C drive, SET). Also try without a swapfile (although this will break multimedia timings)

Are you using a laptop or desktop? It sounds like there is an issue with the memory (either video or system). It might be as bad as the memory is having issues, or as simple as windows is sharing the program's memory pool. (Antivirus?)

Just because some people are not native English speakers, do not assume that they are being sarcastic (or hostile) as WD pointed out; Stress test the implementation until you can document what the current behaviour is doing and what it should be changed to; or submit a patch.

I may be stating the obvious, but it is Dosbox's goal to replace dos in general. Consider the prompt you see (graphically) as the same dos version 2..7 prompt. The only reason you may wish to boot disk images is to load device drivers or specific environments (not everything in dos is emulated.. yet …

Ah, so that might be a hint; there are only instrument names the rest (bars/lines etc) do not appear (it expands to a largish black mostly unused window). [Tested on XP-SP2, .NET 1, 1.1 and 2]

Tested with all the supplied midi's. (I'm driving an SB Xfi ElitePro). It seems to consistently crash on exit (or if I use the MT32 option without my MT32 connected).

Can we get a console only version (something that can run in dosbox)? Depending on required resources, it should compile through Msys/MinGW. Additionally, I am getting a few seg-faults (most likely mem-allocations not being deallocated before exit)

Alternatively you should use the free 're-make' http://sc2.sourceforge.net/ There is also plenty of information on the game history and design. Not to mention updated soundtracks and (fan) spoken dialog.

The problem may be with your Windows mixer -- it buffers (& mixes) audio to the harddisk (somewhere between 4 - 100mb at a time); depending on the drivers, it may allow some tweaking. Check free space too! Also try get a fresh copy of the various support .DLL files, as there may be a "sector …
