* external RAM is now initialized to 0xFF by default: fix Micromachines 2, Dino Dini Soccer
* fixed SRAM 16-bits memory handlers: fix some Sega Sports and EA Sports games (NFL95, NBA Action 95, NHL97, NHL98,...)
* modified WRITE_xxx & READ_xxx macros for better portability and faster memory access on BIG ENDIAN platform
* completely rewrote BIG ENDIAN support in render.c and vdp.c: rendering should be a little faster
* rewrote ROM bankswitch emulation (Super Street Fighter II): ROM access are faster, using memory pointers instead of reading ROM copy from ARAM
* fixed leftmost Window/PlaneA column render and implemented Window bug (as described by Charles Mc Donald)
* improved "Sprite Limit" and "Sprite Collision" detection accuracy
* modified RGB565 Color Palette to use the full available color range (0-31;0-63)
* implemented "cycle accurate" HV Interrupt timings: fix Sesame's Street Counting Cafe, Legend of Galahad (intro)
* improved VDP access timings accuracy (added FIFO emulation): fix Double Clutch
* improved DMA timings accuracy: fix Winter Olympics (E), Arch Rivals and probably more
* fixed HCounter again: Road Rash serie (I,II,III) don't need timing hacks anymore
* fixed VCounter in Interlaced 2 mode: fix Combat Cars "VS-Mode"
* improved Interlaced 2 mode (double resolution) rendering: Sonic 2, Combat Cars ("VS-Modes") look far better
* added TMSS BIOS support (optional)
* rewrote part of the YM2162 MAME's core: fixed internal FM timers handling, removed non-YM2612 emulation code and unused multiple cpu support
* implemented "cycle accurate" FM timers & sound samples rendering
* improved Z80 Interrupt timing accuracy: fix Sonic 3 music slowdowns
* updated Z80 & 68000 cores to last MAME versions
* improved Soft Reset emulation: X-Men 2 and Eternal Champions (random character selection) now work more like on real hardware.
* added full overscan emulation (vertical & horizontal borders) for "pixel perfect" aspect ratio (tested against a real genesis)
[Gamecube]
* fixed rom checksum calculation (only used for rom information)
* some modifications in GX rendering code.
* added support for original Genesis/Megadrive NTSC & PAL video modes: this makes games looking exactly as on original hardware (progressive rendering with reduced resolution)
* added "Aspect" option to switch between ORIGINAL (aspect ratio is fixed and borders are emulated) and MANUAL SET (horizontal and vertical scaling can be manually configured, borders are not emulated)
* added "Overscan" option to disable the original borders color and always use black borders (only used when ORIGINAL Aspect mode is enabled)
* added support for up to 720 pixels horizontal resolution (needed for proper aspect ratio emulation)
* added "TV Mode" option to enable automatic switching to PAL(50Hz) TV mode when the Genesis runs in PAL mode
* added "Xshift" & "Yshift" settings to let you adjust display area position while keeping the original aspect ratio
* added option to disable/enable SSG-EG support in FM cores: this special mode is indeed not properly emulated and some games might sound wrong when enabled
* removed "CPU Type" option, you can also now force Region (JAP/EUR/USA) without reseting the game, choose USA or JAP for 60hz, EUR for 50hz, this can be useful to bypass game region protection at startup.

---------------------------------------------------------------------------------------------------------
[Core]
* you can now switch between FM cores without reseting the game. FM registers value are automatically restored when switching.
* removed the previous VINT timings modification because it brokes some games (Rocket Knight, Thunderforce III,...)
* added automatic Timing configuration (VDP latency, VINT timing & alternate Line Timing) at game loading, based upon specific romname detection.
2007-08-18 13:16:32 +02:00
This means you can still modify some of these options afterwards but they are now automatically set/unset when loading a game which need
special timing fixes. These fixes are also automatically desactivated when the current game doesn't need them.
2008-08-07 14:26:07 +02:00
For information, games that are actually detected and need special timings to run properly are:
2007-08-18 13:16:32 +02:00
.Legend of Galahad & Road Rash series (single line not rendered properly)
.Sesame Street Counting Cafe (don't boot)
.Chaos Engine/Soldiers of Fortune (graphic glitches on scrolling)

* modified PAL framesync a little bit: the 20ms period is now applied between the start of 2 consecutive frames,
no more between the end of the previous and the start of the next one, which seems more correct to me

* added "DVD motor off" feature, like in others emulators
* corrected Memory Card mounting function: EXI_ProbeReset() function was never called if the first mounting attempt failed. Should fix some of the "Unable to mount memory card" errors.
