AGA scummVM and Roland MT-32 

Hello, is it possible to use real hardware for sound, in my case the Roland mt-32?
I was thinking to connect the A1200 with the Roland, in order to play via scummvm the monkey island 1 & 2 of the pc VGA 256 colour versions.
Setup is :
A1200 (blizzard 1230/50Mhz +FPU, 64MB)
Roland mt-32
1084 monitor (I read that vga monitor needed, is it correct?)
OS: classic Workbench

Thanks

As I indicated on:
http://wiki.scummvm.org/index.php/Platforms#Unofficial_Platforms

The ScummVM port to original Amigas is unofficial and not supported. The latest appears to be based on v1.4.1.

If you can select Options->MIDI->GM Device:SEQ and Options->MIDI->MT-32 Device:SEQ, this should send MIDI data to the standard default MIDI interface in the Operating System (assuming the backend code for Amiga has been implemented).

I would test this with a software synth firstly. If this works, then a MT-32 connected with a standard MIDI cable and correctly configured in the Amiga OS should work, but this is totally unknown if this is even possible:
http://en.wikipedia.org/wiki/Amiga_1200#Peripherals_and_expansion

Let us know if you get this working...

Sorry for the delay, but I have a problem when I’m trying to load a game…I’m getting the following message…
“scummvm program error
wait for disk activity to finish. suspend/reboot”
I tried with different hard drives, OS, filesystem, but nothing…

grinder: Sorry, not a clue what that means or why it is happening.

As I said, this is an outdated and unofficial port and so your mileage may vary. If you can find any required source code patches and a toolchain, you may be able to compile and port the latest code to original Amiga, but otherwise you are stuck.

Version 1.6.0 ported to Classic Amiga, this version will support native MIDI (eg MT-32) for the first time Very Happy

This will be my last port of ScummVM to Classic Amiga, I'm moving on to other things and leaving the Amiga scene.

I didn't even attempt to port 1.7.0 as I know that a lot of changes have been made between version 1.6.0 and 1.7.0 and it only just about compiles now (my DEV tools are ancient!).

NovaCoder: Thanks for this. I can't see any newer version on Aminet. Could you provide any required source patches against v1.6.0, a quick build HOWTO and your final v1.6.0 build for mirroring before you leave the scene please?

No problems Smile

Just got to finish testing then I'll be uploading to AmiNet with sources, hopefully early next week.
