Just tested both of those games on my code. Yes, they indeed cause GPF's. Apparently they don't write to the MT-32 in the normal manner. Stranger still is the fact that the game even drives my real MT-32 SNAFU. This leads me to suspect its something amiss in DosBox's MPU-401 code.

Just a reminder that someone actually scanned an official Roland MPU401 manual so you don't have to rely on VDMSound code or those other links in the old DOSBox forum regarding MPU-401's intelligent mode.

See Here:
Re: well, I lost my ebay bids.

If that could help I would like to add that these two adventure games require a real mpu-401 to work with Roland:

Curse of Enchantia,
Innocent Until Caught

I have got a SCC-1 so they work for me, but you cannot run them with MT-32 any other way.

Dosbox doesn't emulate MPU-401's intelligent mode. Sound Blaster cards didn't support this either, only Roland's MPU.
Few months ago I was debugging a demo made by group TPC.
Demo was using some strange MPU-401 commands.
Then I googled a bit and learned about intelligent mode. I couldn't find manual then though.
I also didn't know that my two games are using that mode.

The demo: http://www.pouet.net/prod.php?which=4248

edit - I just checked, Raiden and Lost Vikings don't use any of intelligent mode commands, just UART mode (0x3f and 0xff commands only)

Ahh, the latest SDL.dll from libsdl.org fixed it. Thanks!

Bleurgh, Underdogs. You know, it's a great site and I'd like to think they really do actually pay attention if people point out that something may not be a/ware, but I know on the one occasion I mentioned something to them that my notice seemed to be directed to /dev/null...

Targaff -- you aren't the only one. They seem to bea bit wrapped up in themselves to take notice of others...

If it's any help...
All Sierra's SCI0-games (King's Quest IV, Space Quest III, Police Quest 2, Larrys 2 & 3 among others) require the MT-32 to be connected to a Roland MPU-401 MIDI-interface (or 100% compatible). If you connect the MT-32 to an old ISA Soundblaster the computer freezes when you try to start the game. There is a patch to fix this. It can be downloaded here: http://agisci.cjb.net/ (go to New SCI-drivers)

If I remember correctly the games work without the patch when connecting the MT-32 to my SoundBlaster Live, so maybe the new SB:s are more Roland-compatible than the old ones.

Well, for the exception of some tuning issues, the latest dosbox release works rather well with ALL sierra games... At least PQ 1-3, SQ3, and LSL3 work well for me...

Yeah, but upon further reading of the site, they're about games people have forgotten about, or sleeper hits, or good games that didn't get recognition... They'll usually post links to retail chains for things that aren't that old... So while they do post s lot of abandonware, they'll also post more recent stuff, and if it's out of print/circulation they'll provide a download for it...

They also have a fairly specific notice to the effect that if you know of any game they are currently hosting that is not in actual fact out of print/circulation, then you should let them know so they can remove it accordingly. Now if they actually *did* remove them...

Where can I find the latest downloadable versions of

curses.dll 2.4.0.0
msvcp70.dll 7.0.9466.0
msvcr70.dll 7.0.9466.0

so I can enjoy DosBox to its fullest? My dlls are a version behind these.
http://www.dll-files.com/ has old versions of msvcp70.dll and msvcr70.dll
(7.0.9064.0)

I've got a new release planned soon (source code and everything), and from now on I'll be including the DLL's.

Seeing as you are an official member of the Dosbox team, does this mean that the MT32 dosbox release will become part of the official distribution? or are the two strains to remain seperate?

No. Once I have the emulation perfected (or as perfected as its going to get) the DosBox version will cease to exist and will run only as a driver (Win32 and Alsa) release. It'll still work through DosBox through its MPU-401 emulation, however.

The reasons for this is because the MT-32 emulator is a decently-sized project in and of itself and moreover, requires a several files in order to work. To keep the setup of DosBox simple, it just makes more sense to make the final release of the MT-32 a driver.

It doesn't matter, someone will merge it into DOSBox again sooner or later. Not Everyone Uses Windows(tm)(r).

I don't think Harekiet wants it in DosBox either. As for non Windows operating systems, that's what making the code available is for, and that's what an Alsa driver is for as well.

I wouldn't expect the VMT-32 softsynth to work flawlessly on my Amiga 68060, but who knows 😁

You never know... If you took your MIDI-out from the amiga, use your MPU-401 connection in, and routed it through the Windows driver, it might work flawlessly... Of course I'd say with a modern computer that you'd have one of the most expensive MT-32's available... 😀

Canadacow, you said that you would ship the DLL's in your future releases. However, the latest release doesn't seem to have them and it appears to be practically impossible to track some of the DLL's down. It would serve people if you put them downloadable either included in DosBOX MT or separately.
