Video:Lesson A3 - Simulating functionality for the GBZ80

There may be times where we cannot use functions like the shadow registers, IY or other functionality - either because we're using the GBZ80 CPU (gameboy) or the firmware of a Z80 system need them intact... but we need convert some code that already uses them...
For this reason, it's worth looking at some 'simulated' commands to do basic Z80 functions... they won't be as fast, but they will work!
