骰子君（ DICE:Discrete Integrated Circuit Emulator）是个仿真器，仿真了那些最早期的，不用CPU也不用ROM的街机游戏，所以这些游戏原则上是不会被收录进MAME大百科的。有一个例外，那就是Pong，史上第一个视频街机游戏，被内置在MAME当中作为纪念。所以即使你一个rom也没有，下载了MAME，你还是可以玩Pong。
DICE对系统要求很高，我在i7 2630m上满载只能跑17fps左右，天晓得这玩意的把计算能力用哪里去了！
Many new features in this version, including:
– A complete rewrite of the simulation core, now both significantly faster and more accurate than before
