Dynamic codegen in games might be less of an issue, but instead you get to deal with emulating a MMU among other things. And the point is that all of these issues specific to whole-system emulators mean that static recompilation isn't faster than dynamic, so there's no point in doing contortions to get static working. The original language barely matters when all you have is machine code.

As for where newer consoles are easier, the big thing is that there's more dynamic linking so there's more opportunity for high-level emulation of entire systems. Think being able to emulate entire OpenGL function calls rather than the raw GPU-specific register writes.
