Simple music tracker

Board game

Simple graphic editor (full screen?) with possible imports of different formats (old computer systems included), export can be just 16bpp BMP. Should have zoom, basic paint primitives, flood fill with texture, gradients...

View stars, planets, nebula, galaxies, and other celestial objects

Atari 2600 Adventure clone in which once a level is completed, another level is created that is a little bit larger than the previous one.

Player for movies in special format, can be converted on Mac/PC into it from standard video formats.

Perform calculations with addition, subtraction, multiplication, division, and factorials using both integers and fractions with more digits than the float and integer data types provide.

3D Tetris where the player rotates puzzle pieces in three dimensions and moves them above a well before dropping the pieces into the well.

The original board game Axis & Allies

Puzzle like tool, where pieces are different electric components, you can run the circuit, control switches, measure current and voltage...

Including both Cartesian Coordinates and Spherical Coordinates

Some simple tool to make use of MMBasic's 3D graphic simpler for beginners...

Clone of Activision game River Raid from the ‘80s

Creates a random 2D tile based world in the style of the Ultima series of games

Clone of the arcade game Centipede

Some good AI chess program or engine (Toledo Chess based?). It has to use iterative (non-recursive) algorithm, because of recursion depth limitation of MMBasic (100)...

This should be simple (macro) assembler, that provides CSUB code from Thumb/2 source code.
- output is .INC file, that can be included into BASIC program
- built-in macro for feeding the watch dog
- maybe on begin just use output from this or this and convert it into CSUB
- support for parameters in CSUB

Just look at the Microbridge and imagine the CMM2 could do the hardware-job parallelly offering a dry run, probably GUI-supported and graphically visualized. (> https://geoffg.net/microbridge.html)

exists in javascript might be fast enough on the cmm in Basic ;-)

I don't know if this is possible, as I lack the technical expertise, but it would definitely be worth it! This game from the 1980s is still being updated today, and only requires a text interface. It was written in C and hopefully is not impossible to port to the CMM2. Otherwise its predecessors (Hack or Rogue), would be equally exciting to have as constitute the origin of the Rogue-like games genre.
