OK, but be careful - you will occasionally trip over something where the emulation of it is particularly dire and the real board might be faster; for example with the default flags SD card writes can be a factor of 10 slower than real hardware, so relying on the real hardware always being faster is dangerous. You'll probably get similar CPU emulation artefacts where there are some instructions that are particularly nasty to emulate but really cheap on the hardware. Dave
