FamiTracker CX

This is an old project that I worked on. It has since been discontinued. I'm putting it here for "historical" reasons.

Most of the core code is written by Jonathan Liss (jsr) and other contributors, as taken from the original FamiTracker project at http://famitracker.com/. Almost everything in the famitracker-core directory, with some changes by me, is written by him. Everything else not in famitracker-core is written by Dan Spencer.

What is FamiTracker CX?

FamiTracker CX is a free cross-platform fork of FamiTracker.

FamiTracker CX is created in order to bring the popular NES/Famicom music tracker to Linux. More platforms such as Mac OS X are planned when circumstances permit them.

The optional GUI is rewritten from scratch using the cross-platform Qt 4 library. An ncurses player is also available for terminal nerds.

ALSA and JACK are the two supported audio APIs. More are planned as the Windows and OS X ports are completed.

The software license is mixed GPL v2/New BSD.

Post-Mortem

Challenges

Porting MFC/Win32 to Qt
Modularising the original code into reusable components, as a requirement to allow for many UI frontends. (the original kept all .cpp files in a single directory!)
Lingering undefined behavior created bugs in the Linux version

Coding Mistakes in FamiTracker CX

The "thread pool" is not actually a thread pool, but a message queue.
Using the type_t notation on structs and not typedefs.
Using global state to keep document data for the Qt GUI.
The sound sink implementations abused inheritence, leading to many audio bugs.

If this project were attempted again

Closer coordination with the original author (jsr) to organize the code base to become reusable. There would have been much to ask from jsr, such as keeping a development branch available at all times through Git or some other DVCS. That alone I think would have solved many of the problems being addressed by this project.
