Camoto: Classic-game Modding Tools

Build Status

Camoto is a collection of utilities for editing (modding) "classic" PC games - those running under MS-DOS from the 1980s and 1990s.

This is libgamemusic, one component of the Camoto suite. libgamemusic is a library that can read and write many different music file formats, with a focus on formats used by DOS games.

The library exposes each file format as a long list of "events", such as note-on, tempo change, pitch bend, and so on. This event list can then be manipulated if required, and then written out to a music file in the same or another format.

An instrument list is also provided, which allows manipulation of each instrument used in the song. Current instrument types are General MIDI (patch numbers), OPL register values (used by Adlib songs) and sampled instruments (as used by mod/tracker formats.)

File formats from the following games are supported:

  • Bio Menace (.imf)
  • Blake Stone (.wlf)
  • Commander Keen (.imf)
  • Cosmo's Cosmic Adventures (.imf)
  • Dark Ages (.mid, with OPL patches in sysex events) [read only]
  • Doofus (.bsa)
  • Doom (.mus)
  • Drum Blaster (early .cmf)
  • Duke Nukem II (.imf)
  • God of Thunder (song*, *song)
  • Heretic (.mus)
  • Jill of the Jungle (.cmf)
  • Kiloblaster (.cmf)
  • Magnetic (.bsa)
  • Major Stryker (.wlf)
  • Math Rescue (.cmf)
  • Monster Bash (.imf)
  • Operation Body Count (.wlf)
  • Raptor (.mus, alt tempo)
  • Scud Atak (.cmf)
  • Solar Winds (.cmf)
  • Traffic Department 2192 (.cmf)
  • Trugg (.dsm)
  • Vinyl Goddess From Mars (.mus/.tim) [read only]
  • Wacky Wheels (.klm) [partial]
  • Wolfenstein 3-D (.wlf)
  • Word Rescue (.cmf)
  • Xargon (.cmf)
  • Zone 66 CDFM (.670)

These auxiliary file formats have also been implemented:

  • DOSBox raw OPL (.dro, v1 and v2)
  • Instrument Bank (.ibk)
  • RDOS raw OPL (.raw)
  • ScreamTracker 3 (.s3m)
  • Type-0/single-track MIDI (.mid)
  • AdLib Instrument (.ins)

Many more formats are planned.

The library is compiled and installed in the usual way:

./autogen.sh          # Only if compiling from git
./configure && make
make check            # Optional, compile and run tests
sudo make install
sudo ldconfig

You will need the following prerequisites already installed:

  • libgamecommon >= 2.0
  • Boost >= 1.59 (Boost >= 1.46 will work if not using make check)
  • PortAudio (optional, required only for playback with gamemus --play)
  • xmlto (optional for tarball releases, required for git version and if manpages are to be changed)

This distribution includes an example program gamemus which serves as both a command-line interface to the library as well as an example of how to use the library. This program is installed as part of the make install process. See man gamemus for full details.

All supported file formats are fully documented on the ModdingWiki.

This library is released under the GPLv3 license.
