ASAP is a player of Atari 8-bit music for modern computers and mobile devices. It emulates the POKEY sound chip and the 6502 processor. The project was initially based on the routines from the Atari800 emulator, but the current version has original emulation core.

Input formats

ASAP supports the following file formats:

SAP (Slight Atari Player)

Designed for playing Atari 8-bit music on PCs. All other formats can be converted to SAP. Atari SAP Music Archive (ASMA) is a single big collection of SAP files.

CMC (Chaos Music Composer)

Atari music editor from early 1990s.

CM3 (CMC "3/4")

CMC with modified pattern length.

CMR (CMC "Rzog")

CMC with modified bass sounds.

CMS (Stereo Double CMC)

Stereo CMC.

DMC (DoublePlay CMC)

CMC with 6502 routine executed at double rate of the original CMC.

DLT (Delta Music Composer)

Atari music editor from 1990s.

FC (Future Composer)

Atari music editor from 1990s.

MPT (Music ProTracker)

Atari music editor from 1990s.

MPD (MPT DoublePlay)

MPT with 6502 routine executed at double rate of the original MPT.

RMT (Raster Music Tracker)

Modern Atari music editor running on Windows.

TMC, TM8 (Theta Music Composer 1.x)

Atari music editor from late 1990s. The two file extensions are treated identically and played in stereo. TM8 means it’s stereo (8-channel) music while TMC can be either mono or stereo.

TM2 (Theta Music Composer 2.x)

Modern Atari music editor.

STIL (SAP Tune Information List)

This isn’t a music format. It’s a text file that contains cover information and comments for many music files. This format is identical to C64 STIL. STIL.txt is distributed with ASMA (see above).

You can find some example files in examples.zip.
