An Arduino-based homemade GameBoy and several handmade games.
You can see a video of Minotaur in action here:

- I used a Meduino, which is a smaller Arduino Mega clone. A mega is required because of the memory footprint of the games.
- An Adafruit 1.8" ST7735 based screen with 160x128 resolution using SPI.
- Graphics use the TFT_ST7735 library, which is optimized for speed. https://github.com/Bodmer/TFT_ST7735
- 3 buttons, two for A & B gameplay and a single button on top for game reset.
- A 5-way switch for the joystick, with a custom Sugru molded top.
- A 2xAA battery holder from a Yamaha guitar.
- Sparkfun 5V voltage booster.
- On/Off rocker switch.
- Internal speaker.
- Small vibration motor for force-feedback.
The main GameBoy.ino file displays the game selection menu and drops into the setup routine of the selected game.
A clone of the 1983 Intellivision game Treasure of Tarmin. (later known as Minotaur)
Utilizes a pseudo-3D maze and pretty faithfully recreates the original game given the limitations of the Arduino and drawing speed. I've heavily documented the code, but it's straight C and could obviously be done better. (I'm not a professional developer!)
The drawing routines are the most complex aspect. I found images of the Tarmin maps online, and to fit into memory, I manually binary encoded the 4 walls of each room into a byte - 576 rooms - painful! You can see the maps in the TarminImages folder. The sprites are black and white BMPs converted to byte arrays using image2CPP. Since the Arduino can't draw true 3D at an acceptable framerate, I've hardcoded all of the wall polygon coordinates based on their position relative to the player. There's a small amount of flicker when moving, but I'm pretty happy with how it turned out.
A straightforward clone of Tetris that plays well. I included wall kicks and tried to copy the GameBoy version.
Just like the 1970's handheld Simon game.
A simple snake game I built to first test out the hardware.
