SCUMMVM with MT-32 support enabled?

@pharaohamps I can look into including it if missing.

Thank you. That would be most kind.

I couldn't see a configuration flag on a quick perusal, but I didn't look too hard.

Would launching the binary with the --native-mt32 flag change anything?

It doesn't do anything on my build. According to the About... screen, the version offered with RetroPie includes the following options:

TAINTED, Vorbis, FLAC, MP3, ALSA, SEQ, Timidity, RGB, zLib, MPEG2, FluidSynth, Theora, AAC, FreeType2, JPEG, PNG, Keymapper, virtual keyboard.

Unless MT32 support is compiled in, launching a game with MT32 set as the active music device will either crash out (most of my LucasArts games) or launch using the AdLib music (Sierra SCI games.)

pharaohamps

I reasoned that if MT-32 support was not compiled in, there would not be an MT-32 tab on the config GUI. So I tried setting Options -> Audio -> Preferred Device = MT-32 Emulator, along with MT32 -> MT-32 Device = MT-32 Emulator. I placed the MT32_PCM.ROM and MT32_CONTROL.ROM in the /extras path and started one SCI game and one Lucasfilm game.

Both resulted in segmentation faults, according to /dev/shm/runcommand.log

EDIT: mess fixed. Thanks.

Sorry about the mess, I don't see an option to post using code tags or anything

@pharaohamps would be as simple as adding a perameter here:

https://github.com/RetroPie/RetroPie-Setup/blob/master/scriptmodules/emulators/scummvm.sh#L47

I just don't know which it is :p

@herb_fargus

I've been reading up on it and the following doesn't bode well.

From
http://wiki.scummvm.org/index.php/User_Manual/Appendix:_Music_and_sound#MT-32_emulation

NOTE: The processor requirements for the emulator are quite high; a fast CPU is strongly recommended.

pharaohamps

@mediamogul the notes say the same thing about Fluidsynth and that works fine on my Pi 3.

The emulation is in there, it's just crashing. I'm seeing the emulated MT-32 display - for example it says "SO U WANT 2 B A HERO" when I launch QFG1, which is the same thing that would show on a real MT-32. I know my MT-32 ROMS are good, they're tested and working on the Mac version of ScummVM as well as with Boxer. I think that ScummVM is crashing when loading the MIDI system exclusive messages to the MT-32 but I don't know that for sure.

@pharaohamps

That's encouraging. However, I looked around for a good while for any reference to a MT-32 build parameter and I couldn't find anything. As you reasoned above, it looks like it's enabled, but non-functional.

It used to work fine for me with no performance drop (I completed Monkey Island 2 with MT-32 sound) until SCUMMVM was updated. It looks like we need to use an older build (unless they fixed the error). See here :-

Hooray. More sdl2 bugs (not really surprised...)

BuZz

@herb_fargus I will add an sdl1 scummvm as optional package. Also needed for some controllers

pharaohamps

@BuZz perfect. Thank you.

BuZz

I have added a scummvm-sdl1 module to optional packages (for the rpi only). You will see it if you update retropie-setup.

pharaohamps

@BuZz THANK YOU. MT-32 support is working great using the SDL1 build.

Sent you a little something as a way of saying thanks.

BuZz

@pharaohamps Glad it's working. Cheers!

@pharaohamps , Hello !

I want to get this working with SDL1 also, but i might be doing something wrong ?

I put the roland roms in "bios\scummvm"
i put a Fluid Synth Soundbank in "bios\scummvm"
I set "buis/scummvm" as Extrapath

Then when i set :
MT-32 Tab - > MT-32 Device -> MT-32 Emulator

Midi Tab -> FluidSynth and selected the Fluidsynth soundbank.

But, no sound, only norman "speak + soundeffects"

I tried alot, but now i am tired and need some help

Have you solved your problem ? i only try ScummVM today and like you i don't have MT32 Sound, first i must like you add the mt32 files.

@pharaohamps said in SCUMMVM with MT-32 support enabled?:

THANK YOU. MT-32 support is working great using the SDL1 build.

What are you doing for it ? Only adding some files in BIOS ?
What file names please.

Thanks @BuZz it is the best version for now with smooth mouse movement :)

@darknior said in SCUMMVM with MT-32 support enabled?:

MT32_PCM.ROM
MT32_CONTROL.ROM

The PCM file is pretty much an EPROM chip backup (unaltered) but the Control ROM is basically two EPROM files merged which can be done with a hex editor.

There's a few different versions of the control file floating around. One is older that older Sierra games rely on the bugs. The newer one is more for newer games.

Does anybody have a specific SoundFont they recommend for gaming? They are so varied from a few megabytes to gigabytes. I've been using the FluidR3.

For games like Monkey Island 2 don't forget to check Mixed AdLib/MIDI Mode or you loose some sound effects when using MT-32. They just didn't create them for the MT-32 or were exclusive so they need to fall back to AdLib.

darknior

Thanks a lot @riverstorm for your informations :)

MT32_PCM.ROM (64ko)
MT32_CONTROL.ROM (512ko)

I have stock these files from 2009 ... but not write them with UPERCASE. I will try them.
There is an other control file ? i don't know the one i have, and how to name the two in the same directory ?

You don't write it, i must put all these files in the /BIOS/scummvm directory ?

I've been using the FluidR3

I have some too, collect since 2009 when i made my old Scummvm pack on xbox.

Soundfont - Arachno v1.0 (151.7Mo) -> Maybe the best one, french, made year by year by one guy, excellent for games.
Soundfont - Creative 4 MGM (4Mo) -> Little and made by creative
Soundfont - FluidR3 GM (20011225) (144.8Mo) -> A cool one
Soundfont - GUS Sf2 (5.6Mo)
Soundfont - SGM v2.01 (241.6Mo) -> One of the best ever Soundfont
Soundfont - Titanic 200 GM-GS v1.2 (282Mo) -> Noted the best one to play ScummVM ???

There are some like : Soundfont - Crisis General Midi v3.01 (812Mo) ... so big it will never load or take so many time :(

I have take some different size to try if there is really a difference when i use them :)
But impossible to make them work on Xbox, and now same on my PI :(

In settings we can :
In Audio / choose between Adlib or MT32
         / Emultor Adlib : MAME OPL or DOSBOX ?
In  MIDI menu / GM Ouput : i can't choose nothing
              / i can browse a soundfont -> but it change nothing when i launch Indy 4 Atalntis for exemple
In MT32 / Use it -> but ScummVM tel me i can't use it
        / There are two other options possible to check ... i don't understand why nothing work fine.

Or i put my files in bad bios directory, or bad name ?

Have you a list or a web site where we can found the good informations for these old games to fine configure MT-32 and Adlib sound please ?
Thanks

darknior

Day of Tentacle with ArachnoSoundfont v1.0, so beautiful <3

Riverstorm

Great, thanks for the SoundFont examples I'll try a few out and see how they sound! I know it can be subjective and many seem indifferent or the hardcore aren't using them for games.

The FluidR3 seemed like a decent compromise on size. Do the 200+ megabyte ones work on the Pi?

There is an other control file ? i don't know the one i have, and how to name the two in the same directory ?

You might have the two separate control files? 32k each? I think they need to be combined. If that's the case. The 64K file is probably already interleaved. As far as I know you only need the two files.

MT32_PCM.ROM - IC21 (512KB)
MT32_CONTROL.ROM - IC26 (32KB) and IC27 (32KB), interleaved byte-wise

I have stock these files from 2009 ... but not write them with UPERCASE. I will try them.

Mine are uppercase but I am not sure if they are case sensitive.

i must put all these files in the /BIOS/scummvm directory ?

I think it can be any directory but you'll need to specify it under Options | Path (tab) | "Extra Directory".

To set MT-32 I go to Options | MT-32 (tab) and change "MT-32 Driver:" to "MT-32 Emulator". It's an option in the drop down box.

To set MIDI I go to Options | MIDI (tab), change "GM Device:" to "Fluidsynth" (or the one you're using) and change "SoundFont:" < file path>. It lets you browse to the directory where you stored the files. I stored the SoundFont in the same directory as the MT-32 emulation files.

I don't know if it would work but it might be possible to dump them right in the emulator directory itself (not the roms directory) and not set a path but then you would probably need to modify permissions.

You might check the ScummVM docs:

Also Youtube might possibly have some good tutorials?
