---------------
* improved VBLANK flag accuracy, as observed on real hardware.
* improved DMA operations accuracy, writes are now performed on a scanline basis: fixes Gaiares (flickering title screen).
* improved DMA Fill timing accuracy.
* fixed DMA with bad code values: fixes Williams Arcade Classics (corrupted gfx after soft reset).
* fixed horizontal resolution changes during HBLANK: fixes Bugs Bunny in Double Trouble (2nd stage).
* fixed Vertical Counter in interlace mode 1, as observed on real hardware.
* fixed horizontal border width, as observed on real hardware.
* various code improvments & optimizations.
[Core/Extra]
---------------
* improved savestate format: added DMA, SVP, cartridge mapping & internal registers state informations
* improved unlicensed ROM mappers emulation
* added Chinese Fighters III mapper support
* added Top Fighter mapper support
* fixed Barver Battle Saga mapper support
* fixed cartridge hardware soft-reset (Game Genie, SVP, ...)
* fixed Game Genie registers byte reads
it's now possible to change the input configuration when J-CART is detected: this let you play 6-player mode in Super Skidmarks by connecting 4-WayPlay
.improved Z80 bus reset accuracy
.improved Z80 locks & VDP access accuracy
.improved soft-reset accuracy
.adjusted Horizontal Counter timing in H32 mode (fixes Sonic 3D Blast 'bonus' levels)
.updated win32 port to compile with recent changes
.input code cleanup
[GCN]
.fixed soft-reset (reset switch should also works now)
IMPORTANT: Because of some internal changes, saved states from previous revisions are not compatible !
added an option to disable background "overlay"
changed background image when background is 'pure black'
improved some menu transitions
minor menu arrangement & code cleanup
* 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.
*fixed audio/video desync that could occur after loading a new game
*improved general synchronization of frame execution
*modified ASNDLIB shutdown to prevent potential memory leak with DSP tasks
*changed some global variables to use int type by default for optimization
*some code cleanup
------
* 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)
