(MD for Wii/NGC)Genesis Plus GX 1.4.0 Final - 模擬器

2010.11.02

可以在Wii與NGC平台上執行MD（Sega Mega Drive / Genesis）的模擬器。

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* removed outdated & less accurate Gens YM2612 core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.
* implemented Blargg′s blip buffer in SN76489 core (all channels
are now lineary interpolated)

Core/VDP

* added support for CRAM writes during horizontal blanking (Striker,
Zero the Kamikaze Squirrel,...)
* added support for 2-Cell vertical scrolling in Interlaced 2 mode
* added support for some undocumented mode register bits
* added proper emulation of HV Counter latch: fixes Sunset Riders intro
* added pixel-accurate emulation of mid-line display on/off (Nigel
Mansell World Championship PAL, Ren & Stimpy′s Invention PAL,...)
* improved 2-cell vscroll emulation accuracy, as verified on real
hardware (Gynoug, Cutie Suzuki no Ringside Angel, Formula One,
Kawasaki Superbike Challenge)
* 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.
* improved HCounter accuracy in 40-cell mode, as measured on real
hardware.
* improved color accuracy in VDP highlight mode to match results
observed 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.
* fixed state of Z80 registers on reset (sound issues with Defender &
Defender 2 in Williams Arcade Classics)
* 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.
* implemented 68k undocumented flags behavior for DIVU/DIVS instructions
(Bloodshot / Battle Frenzy)
* 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.
* added Action Replay & Pro Action Replay hardware emulation (only
preliminary Pro Action Replay 2 support).
* added Sonic & Knuckles "Lock-On" support.
* added Cartridge "Hot Swap" feature.
* added missing EEPROM support in more games.
* added VDP lock-out emulation (TMSS).
* improved emulation of copy-protection hardware found in some
unlicensed cartridges (Mulan, Pocket Monsters II).
* fixed Realtec mapper emulation: fixes missing sound in Balloon
Boy / Funny World.
* fixed lightgun auto-detection: fixes default cursor position in
Lethal Enforcers II.
* enabled simultaneous use of multitap & J-CART (Super Skidmarks
6-player mode)
* lots of code cleanup, bugfixes & optimization.

Gamecube/Wii

* implemented custom FONT engine (uses internal IPL font & GX hardware
rendering).
* implemented custom GUI engine (uses GX hardware rendering &
multithreading)
* implemented advanced menu interface (IR pointing, game snapshots,
cheats & saves manager, visual & sound effects, BGM support, etc).
* improved audio/video synchronization to ensure 100% smooth video &
audio playback.
* improved soft-reset button support, now works more like real Mega
Drive / Genesis (model 1) reset button.
* improved lightgun cursors layout.
* added automatic ROM loading feature (last played game launches
immediately when starting the emulator)
* added PAR codes and .pat files support
* fixed lot of stability issues and potential memory leaks.

Wii specific

* added Video Hardware "Gamma" control
* added Video Hardware "Trap Filter" control
* improved Mouse emulation through Wii remote
* compiled with devkitPPC r22 & libOGC 1.8.5 (includes SDHC & USB2
support through IOS58, removes DVDX support)

逃 兵：「說起來有一匹布那麼長。我一睡醒就看到遍地武器和廟裡那個神經病，還發了
瘋地說什麼我是東吳的逃兵，二話不說，拼了命就打。唉呀～那個瘋子又不知
道我是誰，那我還不趕快蹺頭啊！誰知道有一票跟我差不多的人制服了那個瘋
子，又說我立了大功、又說我抓了關公，還要我回去跟什麼主公孫權報喜，走
著走著又不知道碰到什麼鳥兵又開扁，我沒兄弟打不過人家，只有被抓回來啦
！」
