Thanks for your answer, JAL, but I already read the thread, tested "an experimental patch" (which I simply called "dosbox"), found that saved states aren't working after re-lunching Dosbox, sought a dump file around the Dosbox's "capture" folder, ect. I just asked a question to be insure for I …

Does DOSbox holds the save-state in memory or saves it to a hard disk?

Wait, I figured it out. Fast Tracker II plays true 16 bit. The problem was in mixing routines in other players (for example, Cubic Player mixes an S3M-file in 8 bit, but XM-file in 16 bit).

Now I tested it more carefully: Impulse Tracker produces the real 16 bit sound, but other players (CP, DMP, XTC, Inertia) plays as 8 bit. When that players detects SB16, they should plays true 16 bit. I remember how Cubic Player worked on the real hardware and it uses SB16 in 16 bit mode. In Dosbox …

Dosbox 0.73, tested on Mac and Windows. A lot of programs detects SB16, plays the sound through it, but in fact the sound is 8 bit ! The list of programs I tested: - Impulse Tracker 2.14 - Cubic Player 2.0 - Inertia Player - DMP 4 - XTC-player
