Very cool, thanks for fixing font issue .
While you're at it, can you please check why it doesn't produce any sounds ?
With GUS enabled emulator force closes with :
Bad GUS global high read 99
And with SoundBlaster only it doesn't work, when trying to play sample with F5. For reference it does works to some degree in DosBox.

Here is another one, FastTracker. It autodetects and allows to change sound output device on the fly in config.
GUS works great, but SoundBlaster and Pc Speaker wont. SoundBlaster stops after 1 sec and PC Speaker hangs emu.

Managed to get SB16 to work in Impulse Tracker . Other versions of SB wont work, not sure if its a bug in emulator or something in the settings.
With GUS I managed to get past into the gui, by returning 0xff on bad read , but it hangs when trying to play a sample...

It does, don't you think I would have checked?

I am aware of the GUS register read issue, that will be fixed with a number of other GUS changes soon. SB works fine for me.

FT2, there is a bug when using SB16 that I have just fixed. 8-bit Soundblasters and PC speaker work fine for me, so you've most likely got a configuration issue. Sound stopping after one second suggests you've got the wrong IRQ.

You're right, changed IRQ to 7 (from 5) in autoexec.bat and all soundblasters work in both trackers. Strange.
Still have problem with PC speaker in FT2 hanging emulator (including emulated mouse) on my system. I use Award 496/497 bios , i486DX/33 , Windows 7 as host. Do you have an idea what might cause it ?

Another one. Scream Tracker 3. Doesn't start , here's log :
INT 10 : 0E0D 25E5 0000 1950 0ACD:1ADE

In DosBox it goes into gui, but forcecloses soon after playing sample.

Try this version (3.21) of the Scream Tracker 3:
ftp://ftp.modland.com/pub/software/trackers/D … %20Tracker%203/
It is workig for me and PCem v8.1 rev 80 (bc749e3a164e).

It seems to be the same version, just unpacked. But packed version (UPX or whatever it is) works fine on both DOsBox and SPCat, so its likely some bug in PCem.

I don´t think it is compressed with UPX, maybe another pe file packer was used?
If yes, we have to find out which compressor was used to check this a problem of PCem or not.

Just compress (default level) the original size with UPX .
Orig. size = 285051
Packed size = 98761

The new packed Executable is still working on PCem.

Yeah, some other packer. I got the file from pouet site, together with bunch of other trackers I tested.
It could be problem with incomplete coprocessor emulation in Pcem, since DB FE is FCOMI insctuction. http://x86.renejeschke.de/html/file_module_x86_id_88.html
I added it , but there are other unimplemented instructions popping up down the road.
Maybe its some deeper problem that makes PCem fetch bogus instructions.

Does PCEm provide support for Mic / Line-in on it's emulated Soundblaster? I'm still trying to find a PC emulator that does, so I can run DOS eyecandy that uses audio input (Cthuga, Aestesis, etc.)
