Ericde45 Posted January 24, 2022 Author Share Posted January 24, 2022 (edited) original YM licence from Arnaud Carré for st sound library/ YM is the following above. LZ4 part is MIT licence : https://github.com/arnaud-carre/lz4-68k/blob/master/LICENSE i have no licence on my own work, i think that on a out of market console, anything is good to keep it alive, and freely available source can help a lot. ( if you think i shall add a licence file to state it as public and free, please give any good advice. i am not really aware of this ) Quote ST-Sound library is written by Arnaud Carré and is public domain. You can use it as you wish. If you're using it in your project, any credits in any readme file is appreciated As almost all YM files on the web are packed with LZH method, ST-Sound includes LZH depacking code written by Haruhiko Okumura and modifyed/improved by Kerwin F. Medina. Edited January 24, 2022 by Ericde45 Quote Link to comment Share on other sites More sharing options...

The audio quality is great! Quote Link to comment Share on other sites More sharing options...
Ericde45 Posted January 24, 2022 Author Share Posted January 24, 2022 currently the main issue is to create YM7 files, from running ST executables Arnaud Carré did not yet realease its tool to create them. Quote Link to comment Share on other sites More sharing options...
