Mednafen 0.9.37.1

Mednafen 0.9.37.1发表。这个译名就叫“我的模拟器不需要酷炫屌炸天的名字”的模拟器堪称圈内非常低调但是逼格很高的典型。

作为硕果仅存的几个仅支持命令行驱动的模拟器之一（还好有前端），这货就不是为小白用户准备的，但是Mednafen的核心都很不错，特别是其PSX的核心被认为是完全不输于ePSXe，Xebra和pSX等几个高阶闭源核心的完成度。

0.9.37.1

Changements :
– Fixed some issues causing compilation errors on gcc 4.7.x.
– Conditionalize the compilation of shared hardware emulation components(such as 68K, Z80, YM2612, etc. emulators) based on what emulation modules are being compiled in, since support for loading external emulation modules never went anywhere, and if we do eventually add support for it, the exported symbols won’t include the common specific hardware emulation components.
– Fixed some code causing compiler errors with clang 3.4.0.
– Fixed broken loading of save states made with 0.9.37+ on big-endian platforms(0.9.37 regression).
– fflush() before fstat() on the underlying file descriptor in FileStream::size() if the stream is open for writing.
– Added zlib type-size sanity tests to tests.cpp
– _LARGEFILE64_SOURCE and _LARGEFILE_SOURCE are now defined to « 1 » in config.h, for zlib purposes.
– PSX: Avoid undefined behavior(that wasn’t currently causing any problems) in the CPU core.
– PSX: Clamp final SPU output samples(before volume adjustment and resampling) properly; lack of it wasn’t causing any problems per-se, but it could have been an issue in the future.
– GB: Load GBC custom palette from « gbc.pal », not « gb.pal »(0.9.37 regression).

 0.9.37

• Added new netplay commands « /list » and « /gamekey ».
• Rewrote save state rewinding code to be cleaner, and less CPU-intensive when used with systems with large save states like PC-FX and PS1.
• Changed the input-recording movie(via Shift+F5) format
• GB, GBA, MD, VB, SNES, WonderSwan: Save-game nonvolatile memory files are no longer written gzip-compressed.
• MD: Added emulation of the EA 4-Way Play multitap adapter.
• MD: Added emulation of the Sega Team Player multitap adapter.
• MD: Added working Mega Mouse emulation.
• NES: Added support for custom palettes with 512 colors(for de-emphasis bits colors).
• NES: Custom palette loading with PAL emulation now loads from file « nes-pal.pal » instead of file « nes.pal ».
• NGP: Removed various per-game ROM patches by fixing the underlying issues.
• PCE, PC-FX, PS1: Fixed subtly-crackling-sound problem when save state-rewinding.
• SMS, GG: Added support for custom palettes.
• PS1: Reworked disc detection and region detection heuristics to pick up more homebrew PS1 games.
• PS1: Error-out when using a known bad BIOS, or a BIOS from the wrong region.
• PS1: Fixed reverb versus main volume levels; fixes excessive reverb problem in some places in « WipEout ».
• PS1: Increased sound output volume by about 3.5dB.
• PS1: Tweaked Justifier lightgun emulation to fix unreliable horizontal shot positioning in « Elemental Gearbolt ».
• PS1: Added GPU cache emulation; fixes the engine heat effect in « F1 2000″, and mostly fixes the flickering graphics problem in the map screen of « Tactics Ogre ».
• PS1: Fixed broken emulation of an esoteric CDC feature that was causing an assert() to trigger under specific circumstances; fixes an abort with « Rockman 8″ when letting the intro FMV play all the way through.
• PS1: Fixed some precision-related issues in the triangle rendering code; fixes 3D model flickering at three points in « Final Fantasy 8″.
• PS1: Added a rough simulation of a borderline-unstable CDC behavior to fix major problems with « Bedlam » and « Rise 2″.

有趣的是，Mednafen并不是100%原创的核心。像Lynx，NGP，WSC，MD，GB，GBA，NES这些机型都是在流行的源代码上二次开发的。这倒不是偷懒，因为这些源码已经足够健壮高效，只需适配好环境介面就八九不离十啦~~~所以后来的Retroarch也很好的继承了这个废物利用的好习惯，把Mednafen的核心拿来二次开发移植到了十七八个平台上，实在是一报还一报的大快人心…XD

Mednafen已经很久没有新的核心加入了，也不知道大神在忙啥涅？
