GateBoy – A gate-level simulation of the original Game Boy hardware
> Is GateBoy a perfect simulation of a Game Boy?> Actually no, for complicated reasons. The Game Boy chip has a handful of logic gates that operate independently of the master clock and whose exact behavior depends on things like gate delay. These gates create glitches that depend heavily on the physical placement of the gates, the silicon process used to make them, and other weird things like temperature and voltage.This is fascinating, I previously would have assumed that a gate-level simulation would necessarily be perfect by definition.
