I am just wondering why the cycle count for the nestest rom golden log goes from:
line 46: CYC: 333
line 47: CYC: 1
Is this something my emulator should be doing?
CYC is measuring PPU X coordinate. It should range from 0 through 340.

thanks for the response
. I am just trying to test my CPU at this moment and haven't started the PPU yet. Should I just print cycleCount % 341?
PPU cycles are three times as fast as CPU cycles, e.g. "LDA #0" will cause the CYC count to increase by 6. But otherwise that's ... probably safe?
Just ignore the CYC value when you compare the logs.
