Here is the engine's source and a capable Windows version of MESS that can emulate Channel F sound properly (compared to hardware.)

 

There are some example songs and I believe it's documented well enough to be used by those even slightly introduced to code and formatting. (This also being my first code project.)

 

Features:

 

- "Octave" decreasing (really is cycle sensitive)

- "Tempo" decreasing

- "Noise" instrument

- A rather full range of notes without much detune

- PAL support (shitty)

 

v0.21 (Sproutinging):

 

- Addition: Preliminary noise instrument support.

- Change: Added some examples to examples directory by b-knox and Warlord.

- Change: Changed names of some commands.

- Change: Removed "config.inc" and incorporated it back into main.asm

and song.inc. Use song.inc for signature.

- Optimization: Optimized some old code to shorten cycles and conserve registers.

- Optimization: Removed some unnecessary MESS files.

- Fix: Fixed some documentation errors.

- Fix: Fixed binary size calculation. (Back down to 2Kb per binary.)

 

v0.2 (Sprouting):

 

- Addition: Preliminary PAL support. (Notes may be detuned.)

- Addition: "Delay" command to make note sequences faster or slower.

- Addition: "DecOctv" command to be able to approximately decrease an octave.

- Addition: Added ability to warm up CPU before playing.

- Fix: Calibrated NTSC tunings and duration.

- Aesthetic: Incorporated changelog.txt into bottom of readme.txt.

- Aesthetic: Incorporated todo.txt into bottom of readme.txt.

- Optimization: Removed unnecessary code. (Thanks e5frog.)

 

v0.1 (Sprout):

 

- First version.

 

A few examples:

Side note:

 

Battle of the Bits (http://www.battleofthebits.org) will be having Channel F as one of its music formats this year in the competition; as well as many others. Please feel free to enter and have a great time!
