AY Machine

A Discord bot that converts chiptune formats into mp3 upon attaching it on server conversation. It incorporates multiple command-line players for a wide support of common chiptune formats. The bot is also modular as well, meaning the code can be changed to support other players as well.

Tools used

• zxtune: https://zxtune.bitbucket.io/
• furnace: https://github.com/tildearrow/furnace
• chipnsfx: http://cngsoft.no-ip.org/chipnsfx.htm
• arkos tracker: https://www.julien-nevo.com/arkostracker/
• psgplay: https://github.com/frno7/psgplay
• ffmpeg: https://ffmpeg.org/
• openmpt123: https://lib.openmpt.org/libopenmpt/

AY machine uses these CLIs in order to render the tracks. They have to be placed in a separate "tools" folder .

Setup

• BOT_TOKEN must be available in env (supports .env).
• npm install

Run

• Dev (TS): npm run dev
• Build: npm run build
• Start: npm start
• Continuous restart: ./run.sh

Usage in Discord

• Attach a supported chiptune file; the bot replies with an MP3.
• Control AY options (zxtune-compatible formats) by writing flags anywhere in the message, no prefix:
  • clock=<chip_preset|hz|mhz>
  • layout=<abc|acb|bac|bca|cba|cab|mono>
  • type=<ay|ym>
• Examples:
  • clock=zx layout=abc
  • clock=1.75 type=ym
  • clock=1750000
• Skip a specific attachment: include the word ignore anywhere in the message (legacy also supported: $aymignorefile).
• Help: slash command /help shows current presets and usage. When running bot on a server, global command update may take time to propagate.
