frequency

Hello
Why(NES Games) it works in low frequency on the main console 6502 on 3 MHz
But Why should the frequency be high for the simulator? by Atmega and ESP32 ?
thanks

Hi,
Because the ESP32 emulating the CPU (and the console in general) and has to run many instructions for each 6502 instruction.
The ESP32 has also to emulate the video chip and sound which require even more CPU cycles.

Thank you for replying
For example, is it possible to consider a microcontroller for ppu simulation?
That is, to simulate the console with two atmega64 microcontrollers?
