Pym2149

YM2149 emulator in Python, NumPy and a little Cython where it matters. The aims of this project are to demonstrate it can be done in Python, accurate emulation, and interoperability with existing tools. Unlike other projects, we don't emulate the rest of the Atari ST.

• This project is fairly mature, further effort is likely to go towards developing Lurlene and Concern with pym2149 as their chief target
• pym2149 provenance
• Accuracy
• Project stats

System requirements

• Linux is the only tested platform
• JACK Audio Connection Kit for real-time rendering

Install

• Follow instructions at https://pypi.org/project/pym2149/
• YM files typically come compressed, and pym2149 requires lha to automatically unpack them
  • Debian/Ubuntu package: lha or lhasa
  • Windows: http://gnuwin32.sourceforge.net/packages/lha.htm and add its folder to your PATH
• For JACK output you'll need jackd running, I use qjackctl to manage it

Play

• You can get some ZIPs of YM files from http://pacidemo.planet-d.net/aldn/
  • Barry Leitch is a good start
• Now the ym2wav script can convert a YM file to WAV
  • e.g. ym2wav 'Utopia 1.ym' out.wav or just ym2wav 'Utopia 1.ym' - | aplay
• To play via JACK ensure jackd is running (I use qjackctl -s) and then ym2jack 'Utopia 1.ym'
• Bluetooth output is available via PulseAudio by using the PortAudio scripts e.g. ym2portaudio
