ab4638144c [Core/VDP]
---------------
* added support for Master System compatibility mode (Z80 ports access mode), incl. Mode 5 rendering.
* added Mode 4 rendering for both Genesis & Master System modes.
* added alternate BG planes rendering functions (should be faster on PPC architectures).

[Core/IO]
---------------
* added support for Master System compatibility mode (Z80 ports access mode).
* added Master System peripherals emulation (Control Pad, Paddle, Sports Pad & Light Phaser).
* added XE-1AP (analog controller) emulation.
* added Activator emulation.

[Core/Extra]
---------------
* added support for all known Master System cartridge mappers.
* added copy-protection hardware emulation for a few MD unlicensed games: fixes 777 Casino (crash when talking to bunny girls).
(NB: most of those unlicensed games seem to have been already patched by ROM dumpers, main purpose is documenting them)
* added support for Top Shooter arcade board controller. (A=Shoot, B=Bet, C/RIGHT=Coins, START=Start, hold UP on startup to enter service mode)
* improved King of Fighters 98 mapper emulation (registers address decoding is now 100% accurate)
* fixed Game Genie when several codes affect same ROM address.
* fixed EEPROM types for Brian Lara Cricket & NBA Jam TE (verified on real cartridges)

[Core/General]
---------------
* added Master System compatibility mode emulation (automatically enabled when loading ROM file with .sms extension).
* improved savestate stability & compatibility (support for old 1.4.x savestates is preserved)
* various code cleanup & comments.

[Gamecube/Wii]
---------------
* fixed cheat codes handling when several codes affect same ROM address.
* improved input controller detection on menu exit.
* improved key remapping dialog box to match emulated device
* changed Menu key for Gamecube controller to allow MODE button mapping
* fixed DVD not being unmounted on swap (memory leak)

[Wii only]
---------------
* added USB mouse support for Sega Mouse emulation
* compiled with latest libogc: improves USB compatibility & fixes stability issues with Wiimotes.

a4cfc2a77a [Core/VDP]
---------------
* 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

f21a08ebfa [Core]
.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 !

2b78421402 [Core]
------

* 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
