Oldplay plays plenty of older but also news audio formats.

Changes:

– Added UADE plugin * To play an amiga song using the UADE plugin you need to copy the players folder and the score, uaerc, eagleplayer.conf and uade.conf files included in the oldplay folder. Also you don’t need to change the names of the songs since the plugin should handle prefix extensions too. *
– Added new ST-Sound plugin.
– Added new Hively Tracker plugin.
– Added song description tags in vgmstream plugin.
– Added a formats database (formats.db) for vgmstream and UADE plugins. * Basically is a file that includes a list of all supported extensions by these plugins. They support a LOT of formats (~350 by UADE and ~250 by vgmstream) and i haven’t tested all of them, so some may not work. *
