Open Cubic Player


Open Cubic Player original home page is located at and was written by the Cubic Team. It first appeared around december 1994 as a binary-only freeware. It was one of the best module-players if you ask me personally. It had support for many soundcards and module-formats. But as windows grew more and more popular, and users demanding for GUI software, the popularity started to fall off and the project became more or less dead. At some point the sourcecode was opened up for the public under the GNU Public License in a hope that other users might find the code usefull, and perhaps use it for something.

Christmas 2003 I started to look at the the source-code and a little hope to get the software to compile and run under Linux. After 2 months of sparetime playing, I got my first characters on the screen. No sound still, but I had something on my screen. Later more and more code was converted to POSIX and some to gcc inline assembler. Today the project is still not ported finish, but it can be used to beta-testing. There are still a lot of missing features and some strange bugs.

During the porting I also discovered a serious kernel-bug regarding how to handle late FPU-exeptions when returning from a signal-handler. The offending code was located inside stuff/irq.c, and when trimmed down it looked like this (look here)

Source code repository

Source code is now hosted on github in a GIT repository. For snapshots, just poll that tree (and submodules).

$ make install clean
or install package:
$ pkg install ocp

DragonFly BSD


Arch Linux

Package is available in AUR, see

Red Hat / Fedora Project

There is a .spec file in the source repository, but it probably needs some love. Please send in patches!

$ cd /usr/src/redhat/SOURCES
$ wget
$ cd ../SPECS
$ tar xfj -O ../SOURCES/ocp-VERSION.tar.bz2 ocp-VERSION/ocp.spec > ocp.spec
$ rpmbuild -bb ocp.spec
$ rpm -i ../RPMS/i686/ocp-VERSION.i686.rpm

The Fedora Project have packages available - See

Debian / Ubuntu

Debian and Ubuntu have packages available. See, and


ebuilds have been posted at, but not accepted as of today - a maintainer is needed:

$ mkdir -p /usr/local/portage
$ cd /usr/local/portage
$ tar xfj gentoo-VERSION.tar.bz2
$ echo PORTDIR_OVERLAY="/usr/local/portage" >> /etc/make.conf
$ mkdir -p /etc/portage
$ echo "media-sound/ocp ~x86" >> /etc/portage/package.keywords
$ echo "media-sound/ocp X adplug sidplay alsa flac sdl" >> /etc/portage/package.use
$ emerge ocp


A maintainer is needed.

macOS Homebrew

See (blog).

$ brew update
$ brew install ocp
