* improved sprites processing accuracy. * fixed VBLANK transition line checks. * code cleanup and (minor) optimizations. [Core/Sound] * increased FM internal sample size to 32-bit to avoid overflow when adding channels. * added preliminary emulation of YM2612 DAC precision (can be configured to match real console output). * added configurable roll-off for FIR filtering in High-Quality FM mode. [Wii] *added support to enable/disable Video Encoder Trap Filter: can help reproducing "color blending" as on a real Genesis (composite video only). *added support to configure Video Encoder gamma correction.
