dsp-emulator 0.14b1

这是一个毫无存在感的开源多主机模拟器，号称在2001年的时候就发表了…不好意思，单机版真没印象…dsp-emulator模拟了Spectrum、Amstrad CPC 、NES、GB/GBC、ColecoVision、Chip 8还有接近180个街机游戏（居然包括CPS1哦），有点混乱啊，是不是？
但是dsp-emulator有一个很特别的地方，它是用Pascal写成的，用Delphi & Lazarus环境进行编译。作者的理由是他认为Pascal已经足够好了，可以在奔腾级的CPU上以120%的速度运行Spectrum模拟核心…瞧瞧这志气…

话说，单机版大学的时候学过X86汇编、VB、Pascal、Cobol、C，再加上初中时候学的BASIC和LOGO…尼玛也算是个程序员的料啊，为毛一看指针和堆栈就头晕涅？相比之下，BASIC和Pascal还是比较简单的…嘿嘿。
所以，dsp-emulator源代码当中完整的NES、GB/GBC模拟核心，推荐有兴趣的同学应该去看看。
