It does play, but it stutters and the music sorts of loops/repeats itself. It's like hearing two tunes at the same time, with a small amount of time difference between them.
Related amiga players I have: filename "Mark Cooksey", 3.57kb and "MarkCookseyold", 1.77kb.
However... it now works! I renamed it (put .mc at the end), deleted both of these players, and downloaded from exotica the
MarkCooksey Deliplayer file ("MarkCooksey", 3.63 kb, not the "MarkCookseyOld DeliPlayer" link).
Thanks a lot Retro-Nerd and OddbOd.
