The Dreamscript Site was updated with this news:

The DreamScript C API, used principally for the interpreters, will be publically released for general use. Using KOS, the DSCAPI allows intermediate programmers, that actually knows how to program in C to execute pre-made functions to ease the dreamcast programming. This API is also used in DreamScript when a C file is generated by the interpreter. It optimize the code a little bit.

We are currently testing the library and we have currently fair good results. The version 0.1.1 of the API will include the functions: dsSleep, dsJPGLoad, dsPNGLoad, dsGetKeyPressed, dsWaitForKey, dsVorbisPlay, dsVorbisStop, dsJPGSpriteLoad, dsPNGSpriteLoad, dsPrint, dsPrintJapanese, dsSpinDown, dsCDDAPlay, dsCDDAStop, dsCDDAVolume, dsS3MPlay, dsWriteVMU. Not much for now, but it will improve by the time I continue DreamScript. I release this API separetly from the DreamScript future package, because some people who don’t want to code with DreamScript, but want to use DreamScript C API, will be able to do so without having to download the whole DreamScript package.

I hope this will help some people !
