Dan Potter of Cryptic Allusion has released a nev version of his great app for the Dreamcast,this is what is said on his site:

I’ve posted KOS 1.1.1 on SourceForge in both binary and source formats. The source archives contain no binaries that can be compiled from the source. If you want to write KOS programs, then grab the binary archives; otherwise, grab the source archive.I hope to start putting together some independent examples for KOS, distributed seperately from it. Practical things, like an MP3 player like the one on DC Tonic, etc. As a bonus for this release, I’ve ported the libdream examples up to the KOS API. Some are imperfectly ported, some are better, but as a testament to how similar KOS is to use compared to libdream, the porting effort took me about an hour including Makefile adjustment and testing.
