Hi;
Under DOSBOX, SB Pro is T2.
I see no reason for the timeout bug with one module. The First commands are Set Volume.
The SB DSP Code Loop is small, I increased it and I removed the check for SB Timeout in the code. Then, it will no more quit so that you can see if it succeed to play the music.
I also corrected the Vibrato Volume slide (I saw the problem with GSLIDER.MOD), 2 Octave were missing as well in MOD Files. (Due to the changes I did for .XM)
I also finished the SB16 Commands support.
Modules can be played with the Sound Blaster in Signed Mode, I tested with a SB16 (On the 1640 as well), there is something like 10% of improvement (STARDUST.MOD at 31KHz)
I will release this version in some days.
