Can't get Mt-32 emulation to work (loom, mi1)

[Isaac_A_Steiner]

okay, the situation is this:
I have all the setting BY THE BOOK. The roms are working, tested by an other board member. the roland-update is installed
Still, svummvm exits when the first note is supposed to be played.
I get this error message when trying to start loom

Debuglevel (from command line): 9

I'm using today's built on winXP.

The same symptoms are true for MI1 EGA.

What am I doing wrong?
Thx in advance,
Isaac

hmm... every single game crashes

And do they work with Adlib emulation?


Eugene

[Isaac_A_Steiner]

yes, perfectly

[sev]

Weird. Only difference for me was that I have additionally 3DNow! in my processor. I disabled it, and still ran perfectly. What is md5 of your mt32_control.rom?


Eugene

The Md5 is 9513fec4f09a7d327748340ce3a2a59b

Munt is looking for a CM-32L ROM? That's news to me.

Hi,

first of all, I'm so absolutely happy about this whole project. But I've encountered the same problem as the person before: The moment a game tries to play a mt-32 sound the whole scummvm crashes. When I use Adlib everything works fine.

The wannabe-hacker I always am I tried to locate the problem myself and looking at the debug output of scummvm I saw that it assumes (incorrectly) that my processor is capable of 3DNow!. So I changed the following line in i386.cpp (under sound/softsynth/mt32) from:

atti386_Detect3DNow()

Code: Select all

if (result & 0x80000000)
                return true;

to:

Code: Select all

if (result & 0x80000000)
                return false;

and recompiled the whole thing. After that everything worked.

I know that my code change is far from being a bug fix (it simply always tells the emulator that 3DNow! is not available) but the problem seems to be in the detection code. I'm not good enough at assember and C(++) to find out whats wrong for myself but I'm offering to help where I can.

FYI I use gentoo linux (gcc 3.3.6 libc 2.3.5 linux 2.6.16) and have a Pentium M Dothan.
