- Ported MAME's implementation - Corrected FM sound for songs in VF3 that use it - Music tempo now closer to real hardware thanks to emulating two SCSP chips. - Add LegacySoundDSP config option for games with SCSP DSP glitches (ex. engine noises in Sega Rally 2, and loud garbage on Bahn's stage in Fighting Vipers 2) - Renamed SysFPS to "SoundClock" (since raising this appears to adjust the sound frequency).
