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.

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.

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)

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 :/

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.

- 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.

- 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.
