Problem solved. Apparently this skethes only for faces-modules, not for Core-module.
You should be more specific in progrmamm description. Whatever, thanks for answer.

@lukasmaximus
I took GameBoy.ino file from https://github.com/m5stack/FACES-Firmware, Install ArduinoIDE from official site and setup esp32 support. Sketch file is original, not modified.
And now, I get error, as start compile there. here is full text:

i got this message too. on compilation phase. Arduino IDE. It was updated to 1.8.10. I choose M5Stack-Core-ESP32 board.
