dynamic recompiler support #810

If Mesen had dynamic recompiler support would it help Mesen run faster on the pie?

Dynamic recompilers kind of do not make much sense for platforms like the NES and SNES - the timing of all the chips in the system must be followed perfectly to prevent games from breaking, because a lot of games depend on these precise timings - dynamic recompilation does not really allow this. While it's technically possible to some extent to dynamically recompile NES code, you would lose a ton of accuracy in the process, so at that point you're better off just using a less accurate & faster emulator in the first place.

Thanks for explaining it to me.
