Latest build

v0.8.12-ps1 (released 2026-05-14) — short notes on this and earlier versions are at /releases/; the GitHub release pages are at https://github.com/huntergdavis/johnny-castaway-ps1/releases/tag/v0.8.12-ps1.

The CD image ships as a .bin / .cue pair. Both files belong in the same directory. Sizes shown are for the v0.8.12-ps1 upload — the .bin is ~79 MB (~76 MiB), mostly FG2 pack payload routed onto the disc.

Quickstart (DuckStation)

1. Install DuckStation on your platform of choice.
2. Drop jcreborn.cue and jcreborn.bin into a folder.
3. In DuckStation: File → Start File… → pick jcreborn.cue.
4. Hit start. The game runs as a screensaver — let it idle and the scenes will cycle on their own.

There is no menu to “begin.” The game is the screensaver.

DuckStation is the every-commit reference; for other emulators, real PS1 hardware via TonyHax, PS2/PS3 backwards-compat, and the BIOS requirement, see /docs/devices/.

Verify your download {#verify}Optional but recommended if you downloaded the disc image from a mirror

or anywhere other than the official GitHub release page. For v0.8.12-ps1 the SHA-256 hashes are:

To check your local copies, run:

sha256sum jcreborn.bin jcreborn.cue

(macOS: shasum -a 256 jcreborn.bin jcreborn.cue. Windows PowerShell: Get-FileHash jcreborn.bin -Algorithm SHA256.)

If a hash differs from the values above, the file was altered in transit or by a mirror — re-download from the GitHub release page linked above. The hashes are pinned to v0.8.12-ps1; older or newer releases will have different values.

Original Sierra data files

This port ships only the code that drives playback. The original Sierra data files are not included for license reasons.

For development builds (host capture mode), you’ll need:

For the PS1 build, everything you need is on the disc image — the host pipeline pre-bakes the playback packs. End users do not need any Sierra files to play the .bin/.cue.

Controls

The game runs without any input by default. The pause menu is optional and reachable with Start.

Inside the pause menu you can: enter or exit Freeplay, choose a Scene Set (All Scenes, Fishing Only, Johnny Stories, Mary Visits, Visitors, Activities, or Misc & Suzy), open the Scene Explorer chapter-select grid to jump straight to any of the 63 scenes (each with an on-PS1-captured thumbnail), mute sound, toggle closed captions, force day/night, tide, raft, and holidays, advance to the next scene, set the in-game date, move the island anchor, set the RNG seed, and open the sound test.

Freeplay controls

Freeplay launches from the pause menu. It is the direct-control Johnny mode added in v0.5.0-ps1.

Fishing is reached through the pause menu’s Scene Set → Fishing Only option rather than a dedicated joypad button — the Circle-as-fish freeplay action shipped in v0.5.0-ps1 and was retired during the Scene Set rewrite. See /docs/freeplay/#fishing.

The full implementation notes live at Menu help guide, Freeplay and debug mode, and Pause menu.

Real PS1 hardware

It runs on real hardware — the build has been smoke-tested on a SCPH-7501 via the TonyHax softmod path. No officially-licensed disc, no modchip required. Your mileage may vary; treat any boot success as a small miracle.

Where to file a bug

The issue tracker is at huntergdavis/johnny-castaway-ps1/issues. Bugs are tolerated, not invited — there’s no contributor onboarding, just one author and a tip jar that doesn’t exist. See the FAQ.

For security-relevant reports (build/release supply-chain concerns, the published .bin / .cue disc image being mishandled by a download mirror), prefer the GitHub Security Advisories channel named in /.well-known/security.txt.
