The .SAP (Slight Atari Player) Format is a file that contains music data for the Atari POKEY sound chip. There are a whole bunch of tools that can play .SAP files. '[[ASAP] and '[[SAP Player] are two popular examples (there's a whole list of them '[l[http://asma.atari.org/[Here] ). You can make .SAP files using '[[Raster Music Tracker]. The .SAP format only allows 4 channel (mono) mode. Stereo mode is a hack, so battle entries that use this should therefore be submitted in '[[sapx2] or Wildchip catagories.
