SCUMMVM with MT-32 support enabled?

BuZz

@pharaohamps I can look into including it if missing.

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?

I don't think so. I experimented with this about a month ago and even after pointing the software to the MT-32 ROMs and instructing that the games launch with native MT-32 support directly from the launcher, it still failed to launch any titles.

Thank you. That would be most kind.

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.)

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.

mediamogul

@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.

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 :)

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.
