15    MIPS processors are emulated using either a simple binary translation
16    layer (recompilation into native code), which is used on Alpha and i386
17    hosts, or by traditional interpretation (very very slow, but works on any
18    host platform).

20    ARM and PowerPC processors are emulated using a newer dynamic translation
21    system. Performance is somewhere between traditional interpretation and
22    recompilation into native code. However, the dynamic translation system
23    used in GXemul does NOT generate native code, and thus doesn't require
24    platform-specific back-ends. In plain English, this means that the
25    dyntrans system works on any host platform.
