Being cycle-accurate is annoying when you want full realtime if the hosting platform doesn't have enough CPU power to emulate all parts at full speed.
I guess the point is that a pre-compiled version could have HW checkpoints from a slow emulated run, so that it can then run at full speed and just advance the HW to the required timestate when a write is to occur (ie, instead of costly cycle-accurate emulationg, most HW operations can be batched inbetween time-sensitive checkpoints).
Then again, why not just record a video at that point? :P
