http://www.bannister.org/software/ao.htm It's now available in a 4th flavor: native 64-bit Linux. So AO can now play your favorite 8-bit music on your new 64-bit computer :-)
And everyone gets these improvements:
* New, far better sounding engines for NSF, GBS, and SNDH. The YM2149 never sounded so good ;-)
* CAB archive support so you can play S98s from Personal Soundlog Page directly
* Improvements to MOD and S3M playback
* Fixes for crashes with certain RAR and RAW files
* QSFs play at the right speed now
* S98s don't click and many more of them play correctly and at the right tempo
