Flashing

ps2avr(GB) boards use an atmega32a microcontroller and a different bootloader. It is not flashable using the regular QMK methods. 

**Reset Key:** Hold down the key located at `K00`.

Windows: 
1. Download [HIDBootFlash](http://vusb.wikidot.com/project:hidbootflash).
2. Place your keyboard into reset. 
3. Press the `Find Device` button and ensure that your keyboard is found.
4. Press the `Open .hex File` button and locate the `.hex` file you created.
5. Press the `Flash Device` button and wait for the process to complete. 

macOS:
1. Install homebrew by typing the following:   
    ```
    /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
    ```
2. Install `crosspack-avr`.  
    ```
    brew cask install crosspack-avr
    ```
3. Install the following packages:
    ```
    brew install python3
    pip3 install pyusb
    brew install --HEAD https://raw.githubusercontent.com/robertgzr/homebrew-tap/master/bootloadhid.rb
    ```
4. Place your keyboard into reset. 
5. Flash the board by typing `bootloadHID -r` followed by the path to your `.hex` file. 

**Please Note:** You will need to use the `EEP_RST` keycode first, followed by unplugging/replugging the board to get RGB underglow effects to work.
