SpinDizzy 46b1de2238 DSB2 IRQ 2 now fires at 1KHz rather than once per frame, improving 
music timing in Daytona USA 2 and Sega Rally 2. DSB1 CPU timing 
increased from 1MHz to 4MHz, improving music fade timing in Scud Race. 
Thanks to gm_matthew for these discoveries.

Ian Curtis 8aa476aeeb Previous mpeg audio code worked for me in debug mode, but the release build had some serious corruption issues when being built in visual studio. Replaced the old spaghetti code with a more modern implementation. 2019-02-21 14:56:25 +00:00
SpinDizzy bb89bc8e54 Refactor code from previous svn768 (Note : break old savestate compatibility) 2019-02-05 10:03:50 +00:00
Ian Curtis 90faeafbc4 Fix the audio in sega rally2. The game has packed separate tracks into the left and right audio channels. Selecting the correct track fixes the garbled mess. (Spindizzi) 2019-02-01 21:02:02 +00:00
Bart Trzynadlowski f34e25dfc7 Massive internal change: removed CConfig object and replaced it with a hierarchical config object system (Util::Config::Node). Games are now defined in an XML file. Hopefully I didn't break too many things :/ 2017-03-27 03:19:15 +00:00
Bart Trzynadlowski 198a469ff7 Created IEmulator interface, renamed CBus to IBus and CPCIDevice to IPCIDevice. Frames now rendered when emulator paused. 2016-04-10 03:42:41 +00:00
Bart Trzynadlowski c0f679479a Added virtual destructor to CDSB 2016-04-02 21:35:06 +00:00
Bart Trzynadlowski c5d0cb0d97 Added front/rear speaker balance (actually the master/slave SCSP balance). Balance setting is stored in CSoundBoardConfig and can be set on the command line (-balance) or config file (Balance). Valid range is 100 (front speaker volume doubled, rear muted) to -100. The default is 0, both sets at full volume. Balance is applied in the SCSP core before overall sound and music volume settings. 2012-02-09 07:58:07 +00:00
Nik Henson 58954ee4cc Small updates: 
- added methods to CModel3 to access sound board and drive board
 - added methods to CSoundBoard to access 68K and DSB (if attached)
 - added methods to CDSB1 & CDSB2 to access Z80 & 68K respectively
 - small code tweak in DriveBoard.cpp
 - comment tweaks in Model3.h & Model3.cpp

Bart Trzynadlowski 2f5bf43bda Updated copyright information and added headers to all remaining files except debugger. 2011-09-14 19:08:43 +00:00
Bart Trzynadlowski 11d1d61bc2 - Removed BOOL and replaced it with native C++ type, bool. 
- Removed TRUE and FALSE, changed to 'true' and 'false' keywords.

Bart Trzynadlowski d318efe58c - Program settings are now managed by the CConfig class. 
- Moved Logger.h to OSD/, cleaned up comments.
- Command line and config file parsing have been rewritten.
- Began replacing C standard library headers with C++ versions (eg. stdio.h -> cstdio). I think I got most of them, but not all.

Bart Trzynadlowski 12e4d82471 - DSB2 save state support. 
- krom made a minor optimization of the byte reverse routines in ppc.cpp.

Bart Trzynadlowski 52cd9d834b Save state support for 68K, Z80, sound board, DSB1, and MPEG playback. 2011-08-09 18:16:06 +00:00
Bart Trzynadlowski 6a6788952c - Fixed Daytona 2 Advertise song. DSB2 MPEG state machine can now begin playing songs from state ST_GOTA4. 
- krom: Minor fixes to Main.cpp to support wider ROM set names (up to 9 chars) and compilation under MinGW.
 2011-08-03 04:29:33 +00:00
Bart Trzynadlowski ddd6fa92ef - Improved 68K interface. Now supports context switching. 
- CSoundBoard is not derived from CBus.
- Optimized sound board memory handlers (now using switch statements).
- Added DSB emulation (based on R. Belmont's M1 source code).
- Improved ROM loading: only unique ROMs (those not shared amongst games) are used to identify games. The ROM loader will no longer get confused as easily.
- General cleanup here and there, removed unused Render.h file.
