The NONchuk board provides a way to interface joysticks and other devices to the RetroMax. The intention is to use the I2C port on the NONchuk to connect to the Nunchuk interface on the RetroMax (or CMM2).


The NONchuk allows the Nunchuk port of the RetroMax to connect to joysticks and several other devices. Since there are a variety of different devices that can be connected, the NONchuk uses a MicroMite chip (the '170 with MMBasic installed) to run code for the task.


The NONchuck has a console port that can be used as the serial interface for programming the MMBasic code specific to how the NONchuk will be used.


The NONchuk features:
• Based on MMBasic '170 so it can be user re/programmed
• Support Atari (digital/switch) joystick
• Support PC (analog/potentiometer) joystick
• Operate as I2C slave interface
• Operate as serial interface
• Support 16 key keypad
• Support rotary module
• Support analog joystick module


The NONchuck board could also be used as a stand-alone MicroMite ('170 chip) board. For example it could be used with a joystick and various pins from the microcontroller could control relays, LEDs, etc.

This is a compilation of the threads posted by Peter Mather as a background and deeper explanation of the graphics
capabilities of the CMM2. I have taken the liberty (with Peters OK), to post them on the forum with some additional
comments and explanations of recent developments in the hope that they will assist others in realising the full potential
of the CMM2.

Hitomezashi stitching is a Japanese embroidery technique creating a repeating pattern using only horizontal and vertical stitches. This program loosens the patterns using random numbers to create a tapestry with swirling colors. Users can specify from two to five colors in a pattern.

This is an update for Chess. Increased resolution from 800x600 to 1024x768. Provided a different piece set. Improved redrawing of screen process. Also added three chess variants that are at least somewhat playable. Two involve play on a 12x8 board, while the other is played on a 16x8 board. Like before the player plays against the computer with the computer making random moves.

Duplicate entry, sorry. Download link is the same.

Three programs are provided. One is keyboard controlled and another is Wii Controller controlled. The maze can be up to 199 by 99 characters in size. Would like to offer larger mazes than that, but am not sure how to at the moment. The user selects the initial size of the maze and selects one of eight screen resolution modes. The player needs to collect a key on each maze level in order to unlock the door leading downward to the next maze which is a little bit larger than the previous one. Along the way there are six different treasure types to collect. The color of the maze walls changes from level to level. Three MP3 sound effects are used.

Four programs are included. Two programs are controlled via the keyboard and the other two use the Wii Controller. Two programs display 256 1024x768 puzzles while the other two display 86 768x768 puzzles. There are five sizes of puzzle pieces ranging from 12 pieces to thousands of pieces. One selects which puzzle to load or select a random puzzle. The pieces always have a square shape. Pieces can be rotated clockwise or counterclockwise or 180 degrees. Two pieces can be swapped. One can view the completed puzzle and then go back to the work in progress puzzle. There is an option to hide/view the cursor. The program is split into three parts on github. Use 7-Zip Extract Here on the first of the three parts.
