Perform an “Update CoCo-Pi from git repo” on the Administration (Utilities) Menu and then install this latest package. Minor fixes in this version. For those interested in downloading these WIP builds from Ciaran, you can find them here: http://www.6809.org.uk/tmp/xroar/
While not necessarily CoCo specific, CoCo-Pi includes a couple of different Video Game Music Players (VGM). There is a command line one called VGMPlay and a GUI based called Qmmp. You will find some sample VGM files in the /media/share1/vgm folder. If you get a chance, try it out!
