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 Here ).
You can make .SAP files in Windows using Raster Music Tracker or XPMCK.
Alternatively, if you prefer to track on real hardware (or emulating), you can try the following programs:
- Chaos Music Composer
- Music ProTracker
- Theta Music Composer
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.
