Adapted from work by jaromaz at https://github.com/jaromaz/ATtiny-Tetris-Gold.

Hardware

AS programmer I use this one

Software

Connect the avrProgrammer
Insert the MCU

Upload the hex

$ avrdude -c avrisp -b 19200 -p t85 -P /dev/ttyUSB0 -v -U flash:w:ATtiny-Tetris-Gold.ino.tiny8.hex:i

Set fuses

$ avrdude -c avrisp -b 19200 -p t85 -P /dev/ttyUSB0 -v -U lfuse:w:0xf1:m -U hfuse:w:0xdf:m -U efuse:w:0xff:m
