This script reconstructs music tracks from a PICO-8 cartridge by parsing the cartridge’s `__music__` section to identify enabled sound patterns, then mixing the corresponding exported WAV files into complete songs. It reads 64 sound files using the `wave` module, unpacks their 16-bit samples with `struct.unpack`, sums the active tracks per frame, and applies a 61-sample crossfade to prevent looping pops. The code uses `argparse` for command-line arguments and writes the final mixed tracks as new WAV files via `wave.open` and `writeframes`.

Making Chiptune Music using Sonic Pi v2.0

This example shows how to recreate the original NES Mario Bros. theme as chiptune music using Sonic Pi v2.0. It demonstrates the use of four synth types—pulse waves, triangle waves, and FM synthesis—to emulate the NES sound chip, with the melody transcribed from MML notation. The code organizes the music into threads and defines reusable patterns using Ruby lambdas, `play_pattern_timed`, and `nil` rests to structure complex rhythms. It also highlights practical constraints like interpreter size limits and platform-specific performance tweaks.

Pico-8 communic8 interface to JS

Pico-8 communic8 demonstrates a serialization and messaging interface between a Pico-8 cartridge and JavaScript, using a shared memory buffer at `0x5f80` with a header-based handshake protocol. The code defines custom serializers for byte, boolean, number, array, tuple, opacify, and string types, mapping Pico-8 characters to indices for efficient transmission. A coroutine-based receiver queues incoming messages, while the `_update_communic8` function reads header flags and pokes memory to coordinate reads and writes. The example shows how to structure binary data exchange with type-aware packing and unpacking between two runtimes.

Pico:ed Comprehensive Demo (CircuitPython)

This demo turns the ELECFREAKS Pico:ed RP2040 board into an interactive hardware showcase, using the 17×7 IS31FL3731 LED matrix as a live data display. Button A cycles through menu items, Button B activates a feature, and pressing both exits early. A scanner auto-detects external I2C sensors (MPU6050, QMC5883L, HMC5883L) and reports results on the matrix; the on-board RP2040 die temperature sensor drives a real-time readout. Code is a single `code.py` that runs directly from the CIRCUITPY drive, exercising the board's buttons, buzzer, and temperature sensor while adapting to whatever I2C breakout is connected.

PICO-8 Starter LUA code (save this as starter.p8)

This example shows a minimal PICO-8 game state machine with menu, game, and end states, driven by button input. The code defines `_init`, `_update`, and `_draw` callbacks to switch between states, run a countdown timer, and render text via `print` and a black background with `rectfill`. It uses PICO-8’s built-in `btnp` for button presses and Lua’s arithmetic operators for the timer decrement. The visible rendering approach is simple immediate-mode drawing without external libraries or data sources.

SCRIPT-8

This example uses SCRIPT-8, a JavaScript fantasy console for creating retro-style games and visualizations. It renders a colorful, animated scene directly to the canvas using the console’s built-in graphics API. The visualization draws sprites and map data from JSON files, with procedural animation driven by the `requestAnimationFrame` loop. SCRIPT-8’s `pixel` and `sprite` functions handle the drawing, while its input and sound APIs are loaded but unused, focusing purely on visual output. The cassette’s empty chains, songs, and phrases files confirm a minimal, self-contained demonstration of the platform’s rendering capabilities.

Sonic Pi Drum Machine

This example turns a Sonic Pi drum machine script into a visual instrument panel. It shows a sequencer grid for three drum tracks—hi-hat, kick, and snare—with per-step amplitude values (0–9) mapped from the embedded pattern data. The Ruby code defines a `live_loop` and `run_pattern` API to schedule samples, using Sonic Pi’s `sample` and `sleep` functions with a `:pulse` synchronization loop. A selectable `use_kit` command switches between acoustic, electro, and toy sound kits via a `drum_kits` hash. The visualization highlights the code’s structure, not the audio output.

SCRIPT-8

This example loads a SCRIPT-8 cassette from a gist, using its `init`, `update`, and `draw` functions to define a minimal animation loop. The code initializes an empty state, processes input and elapsed time each frame, and renders to the canvas via the SCRIPT-8 runtime’s built-in drawing API. No external libraries are imported; the visualization relies solely on the cassette’s JavaScript and the runtime’s `canvas` context. The sparse project files (`code.js`, `map.json`, `sprites.json`) indicate a blank or placeholder project, with the `misc.json` specifying an iframe version for playback.

SCRIPT-8

This example is a SCRIPT-8 cassette, a self-contained JavaScript environment for creating retro-style games and animations. It demonstrates a minimal project structure with empty placeholder files for code, sprites, maps, songs, and phrases, along with a `code.js` file that defines `init`, `update`, and `draw` functions. The cassette uses the SCRIPT-8 runtime to provide a Canvas-based drawing API, with the initial state set to an empty object and no user interaction or rendering logic defined yet. The `misc.json` file records the specific iframe version of the SCRIPT-8 editor used to create this project.
