[Core/SCD] --------------- * added support for CUE files * added CD-DA tracks emulation (needs CUE+BIN or ISO+WAV images) * added CD fader emulation * added CDD "Fast FW" & "Fast RW" commands emulation * improved CDD TOC emulation (random freezes in Sonic CD, Switch/Panic, Final Fight CD and probably many others) * improved PCM chip synchronization with SUB-CPU (missing speeches in Willy Beamish) * fixed PCM chip emulation (random hangs in Snatcher, missing sound effects in Switch/Panic, Final Fight CD, Wonderdog...) * fixed Word-RAM memory mode on soft-reset (missing logo gfx effects) * fixed SUB-CPU access to unused areas when using PC-relative instructions (Final Fight CD first boss random crash) * fixed CPU idle loop detection on memory mode register access (Pugsy CD first boss slowdown) * fixed Mode 1 emulation (cartridge boot mode) [Core/Sound] --------------- * replaced FIR resampler by Blip Buffer for FM resampling * modified SN76489 core for use of Blip Buffer * improved PSG & FM chips synchronization using Blip Buffer * added Game Gear PSG stereo support * fixed SG-1000 specific PSG noise * fixed YM2612 LFO AM waveform (California Games surfing event) * fixed YM2612 phase precision * minor optimizations to YM2612 core [Core/Game Gear] --------------- * added support for CJ Elephant Fugitive (recently released by SMS Power) * added Game Gear extended screen option [Core/Genesis] --------------- * added support for a few recently dumped (but unreleased) games [Core/General] --------------- * improved ROM & CD image file loading * various code cleanup [Gamecube/Wii] --------------- * added automatic disc swap feature * removed automatic frameskipping (no use) * improved general audio/video sync * various code cleanup & bugfixes 2012-10-13 19:01:31 +02:00			`extern void YM2413Init(void);`
