/***** Time and clock *****/
// ESP8266 is not a very good time keeping device, each one of these little shits has a different clock oscilator.
// it also seems that the temperature also effects the clock frequency so time keeps on drifting and it get's noticable after some time.
// You can play around with these 2 to try and reduce the drift:
#define EMULATOR_CLOCK_SPEED 1000000
// If game time is going faster than it should, increase this value by 1 to slow it down.
// fixed microsecond sleep between each cycle used to fine tune the emulator time drift even more
#define FINE_TUNING_DELAY 1
// If game time is going faster than it should, increase this value
