Sorry for your problems getting the MT-32 emulator to work. Some time this week I intend to post the source code. When I do hopefully it'll become apparent what's going on. Have you been able to get the MT-32 emulator running before?

You're providing an excellent service to the community! So please don't apologize! 😁

To answer your question, I'm a total newbie to the MT-32 emulator. I found out about DOSBox about a week ago and have been loving it! Its nice to be able to play all of those old games again! It was only a couple days ago that I discovered that there's an MT-32 Emulator. I remember how good those games sound with that device! Totally awesome!

I tried installing it on my friend's computer that is running Windows 2000 and I'm getting the same results with the midi files from Quest Studios. DOSBox runs fine on this machine except for when I run a game configured for the MT-32 with the MT-32 emulator running. I get "dosbox.exe has generated errors and will be closed by Windows. You will need to restart the program. An error log is being created." I have no clue where this error log is located, but I'm guessing that it contains the same info as the attachment in my first post. I'm sure it's something stupid I'm doing wrong.

Hiya all,
I've tried running the latest MT-32 version of the Dosbox
(2004-01-18) and am having similar problems.

Here are the dll-versions I'm using:

curses.dll 2.4.0.0
msvcp70.dll 7.0.9064.0
msvcr70.dll 7.0.9466.0
sdl.dll 1.2.5.0
sdl_net.dll 1.2.4.0

I've tried running Monkey Island 1 and 2, Police Quest II
and Conquest of The Camelot. All others except Monkey Island 1 crash
the Dosbox ("Dosbox has generated errors and will be closed" etc).
Monkey Island 1 runs ok (I've noticed the vertical stretching too :).
Sounds ok at the moment, pretty promisingly good actually (The weak
bass is quite noticeable, but that's noted in the "Some known issues that
remain"-part on canadacow's site).

All the best to you canadacow... this really is a great project. Let's just
hope that the project won't be brought down with legal stuff anymore
(Knocks wood).

Heh... my latest changes were supposed to fix memory leaks and crashes.. anyway, the versions of the DLL's I use are:

curses.dll 2.4.0.0
msvcp70.dll 7.0.9466.0
msvcr70.dll 7.0.9466.0
sdl.dll 1.2.6.0
sdl_net.dll 1.2.5.0

Though I doubt its the version that's causing the crashes. I changed the waveforms.raw file in this later version and its much larger than the one in the previous versions. Check for rogue copies of the old one in your path. This may be why its crashing.

I did have an old waveforms.raw in the path C:\WINNT\system32 but I
removed it but it didn't help... still crashing stuff 😦. I tried Space
Quest III, Quest For Glory 1 (EGA) and Monkey Island 2 after removing the
old file from the path (I do have the new one in the directory where I run
Dosbox 😉) but they all crashed. Monkey Island 1 did work as before.

I did the same thing. I had an older version of the file as well. I deleted it and replaced it with the newer one. I also noticed that I don't have the curses.dll that the two of you mentioned. I downloaded the DLL (2.4.0) but it's still crashing.

Something for canadacow:

When trying to run GK1 or LSL3, DOSBox is failing with the following error:

100:00:27.680: First chance exception 0xC0000005 (Access Violation) occurred in "c:\games\dosbox-0.60\DOSBOX.EXE" at address 0x00435931 by thread 1.
200:00:27.680: Second chance exception 0xC0000005 (Access Violation) occurred in "c:\games\dosbox-0.60\DOSBOX.EXE" at address 0x00435931 by thread 1.

Hopefully the address will map back to something meaningful 😀
It's the latest releasem I'd also downloaded the latest versions of the SDL DLLs and removed the old copy of the .raw file - replacing it (in System32 with the new large one).

I'm getting the same problem everyone else in this thread is having. I have the same DLL versions canadacow has, a clean install of the latest DOSBox MT-32 emu (dated 2004.01.17), and then just to be on the safe side I uninstalled the windows driver... no effect.

Is there a site where I can download the previous release? If so, I'll let you know what results I get with that.

I'm having a very difficult time replicating this error. On all the computers I've had the opportunity to test it on, the emulator runs without crashes. Running any of the listed games I have been unable to get DosBox to crash. This is indeed a very odd error. Is there anyway someone could post screen captures or a description of the very point where DosBox crashes runs any of those games?

Update:
I have been able to get DosBox to crash. If any of the necessary files are missing, DosBox will crash when a game that uses the MT-32 is started. In the DosBox directory, make sure the following files are present:

dosbox.exe 495,616 bytes
drumpat.rom 2,566 bytes
patchlog.cfg 1,633 bytes
Preset1.syx 18,555 bytes
Preset2.syx 18,525 bytes
waveforms.raw 1,410,000 bytes
(All the necessary dll files... curses.dll, sdl.dll, sdl_net.dll, zlib.dll, etc)
MT32_PCM.ROM 524,288 bytes (this is the ROM file I can't distribute. If you don't have this file, I can't help you)

Ah! That's it! The MT32_PCM.ROM file! I had it in the same folder as the Windows MT32 Emulator driver, but not in the same folder as DOSBox. I copied it over and DOSBox is working just fine now!

Thanks, Canadacow! 😀

Hey,
now I feel so stupid. How could I have not put the MT32_PCM.ROM
at all in the directory I ran Dosbox from (I've run older versions of the
emulator so this isn't my first time trying the emulator). It's pretty weird
that Monkey Island 1 did work at all. I had the MT32_PCM.ROM in
C:\WINNT\system32\ but not in the directory I ran Dosbox in... well, good
that it's fixed now 😀

BTW the accordion is still off tune in Monkey Island 2. See my post
Bug(s) in the 2003-12-10 release (Dosbox)
Otherwise sounds great... although jerky, but that's just my processor
saying "I need more power" 😉

And yeah, thanks Canadacow for helping out with such a stupid mistake
on my part 😉

canadacow,
please test dosbox version of emulator with The Lost vikings and Raiden.
Both crash dosbox at some point, Raiden during the intro and Lost Vikings
right after intro is played. It doesn't happen when mt32 is not selected.
This was also problem in previous versions of mt32 emu.

After securing an MT-32 rom, I cannot get DosBox MT32 emulator to run... the driver works (with major sound bugs in SQ3, but I'm guessing that is expected) and I wish to try in Dosbox. What is the process for installing, if I already have DosBox 0.60?

Do you have complete instructions for compiling? (I have MS VS.net 2003 from school - MS Acedemic alliance rawks!)

never mind.... Latest SDL fixed it all.

I've checked the version and size of all relevant files, and DOSBox still crashes. The error message I get is this:

"The application failed to initialize properly (0xc0000005). Click on OK to terminate the application."

Canadacow, is there any chance you could just include SDL_net.dll and any other libraries needed (the versions that you're using that you know work) in the ZIP archive on your site? Isn't that sorta customary for distributing binaries?

Use the SDL_NET.dll from the official dosbox release, and the latest version of SDL from the SDL website. this fixed all my problems.

I can't test it with The Lost Vikings and Raiden since I don't have either of those games. Sorry.

Well, this site is advertized on TechTV in Canada, so I guess it's somewhat safe to post here... http://www.the-underdogs.org has both games. It's an abandonware site which, from what I gather(from the commercial), seeks the permission of authors to post stuff. at least if there is a request from the copyright holder to take it down they will... You may wish to check with the site owners to see if their stuff is legal. I just went there for a quick check on these two games.

Raiden worked for the 2 minutes I played it. Vikings Intro plays, but the game crashes MT32 Dosbox. It seemed to work OK in the official dosbox release though (set up for Soundblaster)...
