MIPS processors are emulated using either a simple binary translation |

layer ("recompilation"), which is used on Alpha and i386 hosts, or by |
17 |
|
traditional interpretation (very very slow, but works on any host platform). |

ARM and PowerPC processors are emulated using a newer dynamic translation |

dynamic recompilation; however, the dynamic translation system used in |

GXemul does NOT require platform-specific back-end code. In plain English, |

|
this means that the dyntrans system works on any host platform. |

(PowerPC emulation is still relatively new in 0.3.7, so dont't expect too |

much from it.) |
