------ * improved 68k accuracy (initial reset timing + auto-vectored interrupts handling). * modified Z80 & 68k cores to directly use external cycle count instead of intermediate counters. * improved Z80 & 68k cpu execution/synchronization accuracy, now use Master Clock as common clock reference. * improved PSG & FM chips synchronization with CPU execution (fixed point precision). * completely rewrote sound output processing & mixing: sound chips are now clocked with exact output frame rate to ensure 100% smooth video & audio playback, with no lag or skipping, while still rendering an accurate number of samples per frame. This will also make fast-forward implementation (video AND sound) more trivial. * improved color accuracy in VDP highlight mode to match results observed on real hardware. * improved sprites processing timing accuracy: fixes (un)masked sprites in Mickey Mania (3D level), Sonic 2 (VS mode). * improved horizontal blanking & HINT/VINT occurrence timing accuracy, as measured on real hardware. * improved H-Counter accuracy in 40-cell mode, as measured on real hardware. * optimized Z80 bus status signals * usual code cleanup [GCN/WII] --------- fixed ASNDLIB exit when returning to game fixed audio/video startup sync modified audio back-end engine according to new audio processing core (see above) |
