Page 13: Re-Program The Atmega Using An Avr Programmer
Make sure that the voltage selected on the AVR programmer matches the 3.3V or 5V that you have selected on the GBxCart RW board. The PCB has an ISP 6 pin interface where you can solder male headers. If you don’t wish to do any soldering or would rather keep it clean, you can buy a DC3-6P connector, plug it into the AVR programmer then insert it into the pins and hold it at an angle so the pins touch the pads. - Page 14 Open up the /MCU_Files/ TSB-Program.bat, you will need to change the COM port to suit. Plug in the USB Mini to the GBxCart RW PCB. Run /MCU_Files/TSB-Program.bat and you should see the above result. You should also see the LEDs on the board light up.
