Automatic Story
A deterministic director joins the island, walks, fades, and scenes into continuous hands-off playback.
Independent, unofficial libretro port
The island,
now in RetroArch.
A portable C99 core that brings Johnny's automatic story to modern RetroArch frontends, with direct scene access and the most useful additions from the PlayStation port.
- Release v0.1.4
- 63 selectable scenes
- 640 × 480 software video

Use RetroArch's Quick Menu
Core Options contains chapters, captions, holidays, playback, tide, raft, and sound controls.
Privacy boundary: selected files are read locally by
JavaScript and placed in the player's browser filesystem. They are not sent
to this project's server. GitHub Pages and the published player contain no
original data or user-supplied WAV files.
More than a straight port
Story, accessibility, and control
The core preserves the screensaver-like flow while exposing practical choices through RetroArch's standard Core Options menu.
63 live chapter previews
Jump directly to any audited chapter. Every selection starts the real scene as a live-rendered preview.
Closed captions
Enable captions and tune their size, position, background style, and opacity without altering the scene.
Music & sound
The background soundtrack is a separately licensed CC0 ocean-ambience loop. Volume controls and optional user-supplied original SFX are supported.
36 holidays
Use your local date, a simulated calendar, no artwork, or force one of 36 holidays. Holidays appear as scene emblems without a text banner; the four original emblems are read only from your game data.
Frontend-native controls
Seed, calendar, speed, tide, raft stage, mute, ambience, captions, reset, and versioned save states use standard libretro interfaces.
Authentic runtime capture
The original scenes, through a new portable renderer
The core decodes the user's original resources and renders them through a bounded software pipeline. No SDL window, platform-specific GPU API, or copied game asset is compiled into the core.
The airplane scene at right is the fixed Visitor 1 chapter running in the exact release Web build.
No second menu system
Options belong in RetroArch
Every exposed setting does real work and follows frontend conventions. Dynamic option visibility keeps the menu focused: simulated date/time controls appear only when that calendar mode is active, for example.
- Automatic Story or any fixed chapter
- System or simulated calendar
- 1×–4× playback speed
- Automatic or forced tide and raft stage
- Caption presentation and audio mix

Evidence before labels
The public release is built from clean source, checked for expected formats and libretro exports, and scanned to exclude original data. Linux has real RetroArch runtime evidence; the Web release has strict authentic Firefox video, WebGL, menu, audio-unlock, and cadence evidence.
The authentic browser matrix exercises all 63 fixed scenes: 61 through the ordinary settled window and the short Stand15 and Stand16 scenes through reset-scoped early-motion windows that retain the same quality gates.
Original-data boundary
Port code is open. The game data is not.
This independent project is GPLv3-or-later, but Johnny Castaway's names, characters, artwork, animation, and original sounds remain the property of their respective rights holders. The project is not affiliated with or endorsed by Sierra, Dynamix, or those rights holders.
No original resource archive, proprietary extracted game sprite or
holiday image, or original sound sample is included. You must supply a legally
owned RESOURCE.MAP and RESOURCE.001.
