45e03f9572 Changed bx_bool to bool type in the harddrv, cdrom, hdimage and sound code. 2021-01-31 15:44:39 +00:00

93b51df2cb Including stdint.h is not required here, since we are using Bit8u, Bit16u etc, 
(thanks to Ben Lunt).

fd690a3a31 Fixed compilation errors found on Cygwin64 
- The 'Bits' type used in the opl files is incompatible with Bit64s. Modified
  typedef to fix this issue.
- On Windows use Sleep() directly, since msleep() doesn't exist in Cygwin.

601493c89a Moved output volume calculation to a separate method and prepared volume 
control for the FM output.
TODO #1: handle volume control in the opl code.
TODO #2: check if the output level calculation is correct.

add5b1e61d Some work on the Bochs sound support. 
- OPL3: Added support to change the samplerate of the generator.
- SDL sound: convert wave packet to 16 Bit signed stereo format.
- Increased the maximum size of a single wave packet for playbck/recording.

cf888edf81 Removed most of the incomplete legacy FM OPL emulation part of the SB16. 
Only keep the OPL timer code required for chip detection. Started implementing
save/restore support in the OPL3 code ported from DOSBox.

fb265dc532 Ported OPL3 emulation from DOSBox. 
The code currently only works with the SDL sound output module and at 44100 Hz,
with 16 bit stereo signed little endian format. FM volume control and
save/restore support are not implemented yet. The legacy code for generating
MIDI notes still works and will be removed when mixing support is implemented
in all sound modules.
