I’ve decided to officially release the engines (scripting, physics, sound and 2.5D rendering) behind Kobo II as Free/Open Source, in order to make the game available to basically anyone with OpenGL and a C compiler.
Don’t expect this to be seriously usable production code! I am indeed using it for Kobo II and various tools, but I implement only the very features I need right now, so expect a generally odd feature set, little documentation and a few dangling wires.
First out is ChipSound, which is now under the zlib license.
Direct download: ChipSound-0.1.0.tar.bz2 (75K)
Included with this is a small SDL based test program that demonstrates how to load, play and control sounds, and how to implement oscilloscopes by wiring an application callback to the “master” voice.
The included work-in-progress demo songs belong to Kobo II, and are NOT covered by the zlib license. They’re only provided as examples of what can be done with ChipSound. More info on some of these songs can be found here, here, here and here.
