Normally static recompilation of video games breaks down due to self modifying code. If you're going to have to have go through the motions of JIT anyway (and in places where, if they're going through the motions of self modifying code, it's probably computationally expensive code at that), then you might as well go whole hog. That way you only have to build one kind of compiler, and you can take advantage of profile information for everything.

But the 360's security model specifically out rules self modifying code. And this is enforced by the hypervisor; the system is W xor X, and the transition of a page from W to X has to be accompanied by signatures signed by Microsoft's private key. Nobody, including the kernel, can modify their code.

That might make this one of the first platforms where the static recompilation scheme might make sense in the long term architecture of the emulator.
