@retrovm/media

Cassette tape encode/decode library for retro computers — ZX Spectrum today, more systems planned. Works in Bun and Node.js.

Install

bun add @retrovm/media

Use

import { Tape, zxtap } from "@retrovm/media";

const tape = zxtap(await Bun.file("game.tap").bytes());
for (const block of tape.parseLogicalBlocks()) {
  console.log(block);
}

tapview

An interactive terminal browser for .tap files ships as the tapview bin. After installing the package, run:

tapview game.tap

Development

bun install
bunx tsc --noEmit   # type-check
bun run build       # compile dist/ for publishing (bun run <file> works directly on src/ without building)
