Still bashing away at the MESS FM Towns driver. I've now added some of the all-important CD audio functionality to the CD-ROM controller. Not an easily task, when no games run, and there is virtually zero documentation on it (that I could find, at least). But, since MS-DOS does now run, there's always a possibility of some small, simple DOS application that can play CD audio tracks. Here's one! :)

So, what I did, was download the exe, and copy it to a normal PC MSDOS disk image via WinImage. Then boot DOS 6.2 in Unz (since MESS only supports the normal, for Japan, 1.2MB 1024 byte sector format currently), and copy the exe to the DOS 6.2 floppy. This boots in MESS, and CDPLAY.EXE can be run there.

If you're having trouble imagining how it sounds from a screenshot, there's footage from an actual FM Towns Marty, running Raiden Trad – http://www.youtube.com/watch?v=9gziChneci4
