Camoto Online is a collection of integrated utilities for editing (modding) "classic DOS games", those running under MS-DOS on the PC from the early to mid 1990s.
As of October 2021, there is still plenty of work to do! The web interface is capable of editing graphics for supported games (really only Dangerous Dave at this point) but it can't do much else.
The focus is now on the level editor and the music UI as, after so many years of talking about it, I have yet to finish a DRO/IMF to MIDI converter that can convert the instruments in real time while the song is playing.
- gamecomp.js applies and removes various compression and encryption algorithms. It can also remove LZEXE and all known PKLite versions.
- gamearchive.js extracts, creates and modifies game archive files. These are just like .zip files except many games use their own custom format.
- gamemap.js provides a consistent interface to 2D grid-based game levels.
- gamegraphics.js allows conversion to and from many different graphics formats, as most games used their own custom ones.
- gamemusic.js reads and writes music notation files used to store music for many games.
- gameinfo.js ties everything together into a unified interface. Camoto Studio only needs to talk to gameinfo.js, which handles things like which files are required to load which levels, which palette applies to which graphics files, and so on.
- Camoto Studio Online is a web-based interface to viewing and modifying any game supported by gameinfo.js.
