[06/30/10] version 1.4.0 (Eke-Eke)
|
||||
----------------------------------------------------------------------------------------------------------------------------------------------------
|
||||
|
||||
[Core/Sound]
|
||||
|
||||
* completely rewrote sound processing/mixing: sound chips are now clocked with exact output framerate
|
||||
to ensure 100% smooth video & audio playback, with no lag or skipping, while rendering an accurate number
|
||||
of samples per frame and keeping PSG & FM chips in sync.
|
||||
* improved PSG & FM chips synchronization with CPU execution (fixed point precision).
|
||||
* improved YM2612 core general accuracy (SSG-EG, CSM mode,...) (based upon Nemesis recent tests on real hardware)
|
||||
* improved YM2612 LFO emulation accuracy: fixes "Spider-Man & Venom : Separation Anxiety" (intro)
|
||||
* fixed YM2612 bug with Timer B: fixes "Langrisser Hikari II"/"Der Langrisser II" (Sega logo)
|
||||
* fixed YM2612 context saving/loading.
|
||||
* fixed YM2612 state on reset.
|
||||
* removed outdated & less accurate Gens YM2612 core
|
||||
* added configurable YM2612 DAC resolution emulation.
|
||||
* added configurable & faster FIR resampler (thanks to Blargg & AamirM), removed libsamplerate support.
|
||||
* added configurable Low-Pass filtering
|
||||
* added configurable 3-Band Equalizer (thanks to Neil C).
|
||||
* added an option to boost SN76489 Noise Channel.
|
||||
* adjusted SN76489 cut-off frequency.
|
||||
|
||||
|
||||
[Core/VDP]

|
||||
* added support for 2-Cell vertical scrolling in Interlaced 2 mode
|
||||
* added support for some undocumented mode register bits
|
||||

|
||||
* improved FIFO timings accuracy: fixes Sol Deace intro
|
||||
* improved sprite masking accuracy (thanks to Nemesis for his test program)
|
||||
* improved sprites processing accuracy: fixes (un)masked sprites in Mickey Mania (3D level), Sonic 2 (VS mode).
|
||||
* improved HBLANK flag timing accuracy: fixes Mega Turrican (Sky level)
|
||||
* improved horizontal blanking & HINT/VINT occurence timing accuracy, as measured on real hardware.

|
||||
|
||||
|
||||
[Core/CPU]
|
||||
|
||||
* updated Z80 core to last version (fixes interrupt Mode 0 timing and some BIT instructions).
|
||||
* fixed some Z80 instructions timing.
|
||||
* improved Z80 interrupt accuracy
|
||||
* improved 68k accuracy (initial Reset timing + auto-vectored interrupts handling).
|
||||
* improved 68k timing accuracy for DIVU/DVIS (thanks to Jorge Cwik) & MULU/MULS instructions.
|
||||
* improved Z80 & 68k cpu execution/synchronization accuracy by using Master Clock as common reference (now run exactly 3420 M-Cycles per line).
|
||||
* modified Z80 & 68k cores to directly use external cycle count instead of intermediate counters.
|
||||
|
||||
|
||||
[Core/Extra]
|
||||
|
||||
* added Game Genie hardware emulation (Game Genie ROM is now fully supported).

* added SVP faking: display 2D graphics in Virtua Racing (the game is however still unplayable)
|
||||
* added support for more internal IO registers: fixe some unlicensed games (Wisdom Tree games...)
|
||||
* added preliminary support for unmapped protection device: fix some unlicensed games with special built-in hardware (Squirell King, Lion King 2...)
|
||||
* added "Soft Reset" combo (in game, use L+Z triggers): this should be like pressing the RESET button on a real Genesis and this is required
|

in some games to enable special features or even complete the game (ex: X-Men).

- 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.

special timing fixes. These fixes are also automatically desactivated when the current game doesn't need them.
