After applying cache fix nothing definite as far as I remember (I ran it last time almost 2 week ago, need to rerun). Code always go through emulator now and check direction flags to update SI/DI accordingly. Emulator is a big switch and it calls various callbacks that may also slow things down.
We can have it set up a fast path. Similar to how real hardware optimizes 'rep movs' to copy complete cachelines.
The emulator does all the checks, sets up a callback to be called on completion or when an interrupt is made pending, and lets x86.c do all the work.
