This small game console is made of Waveshare RP2040-PiZero and 1.3inch 240x240 IPS LCD display HAT. The games are stored statically in the flash and the size of flash is 16MB.
Game List: Tic Tac Toe, Sokoban, Water Sort, Number Slide
You can navigate the menu using joystick button on the HAT. Press the center of the joystick to enter. KEY1 act as a back button. On Sokoban, Water Sort games, the KEY3 act as undo and KEY2 act as reset.
Settings and the game progress are stored in the special area of flash.
Some pins of the SD card interface are shared with the buttons of the LCD HAT. Therefore, we cannot use the SD card to store games. Also, the display does not expose the TE pin. So, we cannot prevent the tearing effect.
Hold the boot button on the board and plug it to PC. New removable drive will appear in My Computer. Copy the Napoleon_Console.uf2 file into that new drive. Unplug the board and connect the board with LCD display HAT. Power up the board using the USB connector.
Even if we put rp2040 into deep sleep mode, other accessories will drain the power from the battery. Therefore, we will use a switch to cut off the battery power from the system. The positive wire of the battery will go through the switch. You will need to turn ON this switch when charging the battery.
