This page contains programs originally written for other operating systems (generally Linux or Unix) that I have ported or recompiled to run under OS/2 and eComStation.


This is a tentative attempt at porting MKVToolNix version 2.0.2 to OS/2. These ports are highly experimental and have not been tested extensively. Use them at your own risk!

MKVToolNix is a set of command-line utilities for creating, disassembling, and otherwise manipulating Matroska multimedia files.

See the README for more information.



Potrace is a command-line utility for "tracing" a bitmapped image to generate a scalable vector image. This package contains OS/2 binaries. See the release notes for more information.

Note that Potrace itself operates on black and white bitmaps only. Greyscale images can be converted using the included mkbitmap prefilter program. Colour images require more advanced techniques; see the Potrace FAQ for details.

Potrace was written by Peter Selinger.

TiMidity++ is a music player for MIDI files and similar formats. It is a 'standalone' player: it does not depend on MMPM/2 for its operation.

TiMidity++ version 2.13.2 for OS/2 (release 3) is a refreshed port of version 2.13.2, based in large part on Darwin O'Connor's older 2.10.4 port but with added OS/2 GUI (Presentation Manager) support. (This GUI is based on Darwin's old TimidPM interface, but significantly enhanced and updated.)

See the OS/2 release notes for a more description.

Note that you must install a set of sound samples in order to play most MIDI files with TiMidity++. As a convenience, I have packaged the highly recommended EAWPatches collection (below); this can be installed seamlessly together with TiMidity++ if the both WPI files are in the same directory.

XJDIC is a text-mode Japanese/English dictionary program, written by J. W. Breen, which is designed to use the freeware EDICT and KANJIDIC Japanese dictionaries.

I've ported XJDIC version 2.4 to OS/2 using kLIBC/GCC 3.3.5.

XJDIC accepts a search string in English or Japanese, and returns a list of matching results from the dictionary. Japanese text is displayed in kanji and hiragana/katakana, not romaji — so if you cannot read at least hiragana (Japanese phonetic characters), this program is probably not for you.

There are two versions of the program: a normal, standalone executable (which most people will prefer); or separate client and server executables which allow you to keep the dictionary files on a different computer from the one you're sitting at, possibly for multiple clients to use (you could even use somebody else's server if one is available to you). Both versions are included in the ZIP file below.

See the OS/2 program notes for more information.

Note: Jim Breen also maintains a WWW lookup interface for EDICT which provides similar functionality through a web browser. Check it out here.
