It's possible to emulate the functionality OK, but very difficult to
emulate the timing. For game code, this can be a big problem. Any code that isn't synchronized, if at all, to external events or only is required to meet certain deadlines, is broken by design - e.g., all code written to execute fixed delay loops. I also consider calibrated delay loops to be pretty much broken. Code relying on ryce conditions to work should be deleted, and the perpetrator given the treatment reserved in China for traitors. Unfortunately, even well-respected OSes contain some of this type of code, mostly in drivers. Jan |
