Snes9x 1.57

Snes9x发布了它的最新正式版1.57。作为模拟器世界中的活化石，我对它没啥特别的要求，活着就可以啦。本次更新主要还是模拟精确度方面的提升，而且已经同步的libretro分支，同学们都不用重新下载，只需要更新RA Core即可。

同学们可能奇怪，都开发了20多年了，Snes9x应该是精确的秒天秒地了吧，还更新啥？嗯，我来为大家介绍下，Snes9x非常谦虚，在各种兼容性测试中不卖老资格，经常垫底。为我们圈子里带来了历史最悠久的一个老梗：完成度和Snes9x一样…意思是刚过及格线。

Snes9x登场与1997年末，那时候Win95,Win97,Win98正当红火，很多软件命名都喜欢带年份，什么KOF97，FIFA96什么的，俗，忒俗了…于是最初由Jerremy Koot在1996年编写的Snes96在停止维护后，由Gary Henderson接手维护改名为Snes97。但是写到年底，Jerremy Koot又回来帮忙，叫Snes98不太合适。所以融合了Snes96和Snes97的特性的最新SFC模拟器就叫Snes9x咧…

我记忆里，最早的游戏机模拟器就是从93年开始逐渐在万维网上流传的，那时候主要是GB和FC，所以97年时候的SFC模拟器的关注度基本和我们现在的PS3模拟器差不多。所以Snes9x和它的96,97前辈一路过来和很多其他SFC撕过逼。

1996年，Snes96和ESNES大战，基本不相上下，ESNES是有记录的最早的SFC模拟器，登场于1994年。

1997年，Snes97和NLKSNES大战，速度上完败于NLKSNES。

1998年，Snes9x再次败于宿命中的对手ZSNES，以后一直是输多胜少。

直到ZSNES的重汇编构架不再适应WinXP以后的新一代操作系统而逐渐停止更新之后，Snes9x才当之无愧的登上了最著名SFC模拟器的宝座。可惜依然不是最佳SFC模拟器，因为那时byuu的bsnes（后来叫higan）已经来了。据说迫使byuu开发一个易用性极低的SFC模拟器的原因就是他实在受不了Snes9x的低精确度。

但是，Snes9x是最早的开源模拟器之一。在Retroarch之前，Snes9x就被移植到几乎所有平台。现在大家看到的各种移动平台上的SFC模拟器，基本都是源自于Snes9x的血统。虽然很多专家取笑Snes9x不够精确，但是Snes9x的兼容性一直想当优秀。在能玩100%游戏的优势之下，什么颜色图层不精确，声音不精确，test ROM跑不起来都是小事。

所以，Snes9x的励志路程告诉我们，如果要取得最后的胜利，首先你要够命长，让敌人倒在你前面；然后要能生，多子多福。冠绝天下，独步武林，没人继承，也终究是黄粱梦一场；最后就是全面发展，做的差点没关系，只要会做就行。

最后，我认为，在号称99.99%精确的higan面前，Snes9x可能还要更新个几十年的样子，我们有的是时间。
