asmsx is a cross-assembler that was created by Eduardo “pitpan” Robsy of msxdev competition fame. After a decade of excellent work, Eduardo decided to discontinue MSX-related activities. In April 2011 he announced sale of all right to asmsx on eBay. cjv99 won the auction and released source under GPLv3 license.
For the past two years I was hoping someone will take over the project, translate it and continue with further development, but no one did. I decided to give it a try myself. asmsx is free software, so it was pretty easy start. I now post my patches to asmsx-cleanup project on Github.
December 17, 2013 update: translation is now complete!
December 29, 2013 update: moved project to GitHub
