Thank you for the heads up and good work. 😎

EDIT: Your link doesn't seem to work right now... 😕

I have posted a message on Quest Studios forum

Congratulations!
I can't even get David Wolf to play MT-32 music using a real MT-32 connected to a real Roland MPU-401 interface installed in my 486 DX2-66 running MS-DOS 6.22...

I don't know if these games use intelligent mode, but I had problems getting the following early Legend Entertainment games to work with the hardware mentioned above:

Spellcasting 101, 201 & 301
Gateway 1 & 2
Eric the Unready
TimeQuest

I think I changed some IRQ-setting on the 486's IO-card to get them to work. Most other games supporting the MT-32 had worked perfectly without having to change this.

And (as I mentioned somewhere else in the forum) all Sierra SCI0-games (King's Quest 4, Space Quest 3, Larry 2 & 3, Police Quest 2, Quest for Glory 1 & 2, Codename Iceman, Colonel's Bequest, King's Quest 1 Remake, Conquests of Camelot, Hoyle 1 & 2) fail to work with an MT-32 connected to the MIDI-port of a SoundBlaster. (there is a patch to fix this)

I implemented most "intelligent" playback functions of original Roland's MPU-401 for use with Dosbox and Roland MT-32 emulator

Will it be possible to use it with real mt-32 too? Will it be implemented in the rjpa's CVS so we could test it with real mt-32?
(I know that dosbox's old mpu-401 emulator was already emulating some intelligent mode instructions, and we could use it with real mt-32)

It should work (in same way as with old emulator). If this will be included in dosbox source, then it'll be in the builds.
Legend ent. games are still problematic (sending wrong data to mt32).

Spellcasting 201
Timequest
Spellcasting 301
Frederik Pohl's Gateway
Companions Of Xanth
Gateway II: Homeworld
Eric The Unready

^Those games work properly with mt32 (on my Duron with SCC-1).

I couldn't force Spellcasting 101 to work with mt32 (even on a 386 with scc-1)

Spellcasting 101 works too.
For all the above games you can use "game mt32 2 330",but with s101 it will freeze though it works with "game mt32 2" and "game mt32".

A-10 Tank Killer (Dynamix)
David Wolf (Dynamix)
Laser Squad (Krisalis)

^They work with my scc-1 and require it

Thanks. No amount of nagging seemed to be helping. 😁

Qbix merged the patch with CVS today, so it'll be in the builds soon.
Please check patch page at sourceforge.net for known bugs/problems if you find any bugs 😦

Note: intelligent mode emulation is disabled by default (compatibility problems with few games). There is option in the config file, "midi" section.

Legend Entertainment games (Spellcasting, Gateway, etc.) don't work. I couldn't configure A10 to play MT-32 sound (The Underdogs version).

Legend games "work" to a certain extent if the PIC patch is also merged, but the timing is waaaaay off.

V.

I merged the pic patch as well.
I also changed the priorities a bit. So maybe it's better now

I think I finally know what is wrong with Legend games. Emulator expects that interrupt routine sends data to mpu401. But in this case game sends data after interrupt is finished.
Currently emulator only receives data until irq is over.

Srecko: underdogs' version of a-10 tank killer doesn't have install.com file (I wonder why...).
Just make a file a10.cfg and edit it with hex editor: 08 10
It works with emulator.

OK, Legend games work now and changes are in CVS. Slowdown problems are also gone.
Thanks for that A10 hint.

i have found another game that wasn't supported by previous dosbox's mpu-401 tricks:
Zeliard (Game Arts/Sierra'91)
It works in emulator now.

some more, working now 😉 :

Sabre Team (Krisalis '94)
Shadoworlds (Krisalis '93)
Hired Guns (Psygnosis '93)

It Came From The Desert (Cinemaware '91)

works with my scc-1 and require it, but doesn't work with emulated intelligent mpu-401

Re: It came from the Desert - MPU-401

huge/i
^ this runs setup

another game:
"Corporation" (Core Design '91)
works, but...:
