13 Sentinels: Aegis Rim - PC Port

Version 0.1.0, the first release, for Windows (ZIP) and Linux (AppImage) together. The game installs, boots and plays on Windows with the Vulkan renderer. The Linux AppImage has the same applicable feature set and is experimental: it is built and checked headlessly but has not been played through yet. See docs/LINUX.md.

Compatibility note: CUSA19610 USA is the primary development build and has received the most gameplay testing. The Europe, Japan and Asia builds have been verified to install, boot, start the game and pass the port's focused compatibility checks, but they have not been fully played from start to finish. Region-specific issues may still exist.

No game files are included. You need your own legally obtained copy of the game as a decrypted (fake) PKG. This project is not affiliated with Vanillaware, Atlus or Sony Interactive Entertainment.

Packages are identified by their param.sfo (TITLE_ID, CONTENT_ID, CATEGORY, APP_VER, VERSION) and their executable hash, never by file name; an update is only laid over the base of its own title ID. The European 1.01 update also comes repackaged for older firmware; both packagings are the same game and install as the one build. The European executables are the American ones (1.00 differs only in a build date string), so they share the American feature sites.

Using it

1. Windows: run 13_sentinels_aegis_rim.exe; the launcher opens. Linux: put the AppImage in a folder you can write to, chmod +x 13SentinelsAegisRimPC-v0.1.0-x86_64.AppImage and start it; the launcher opens.
2. Play → Install game... and select your region's base package. It is unpacked into game\ next to the program (Linux: next to the AppImage) (3.5 to 5 GB).
3. Optional: Play → Install update... and select an update of the same region (USA 1.01 or 1.02, Europe 1.01, Japan 1.03 or 1.04; no earlier update is needed). Each update gets a folder of its own made of hard links to the base plus the update's files, so the base stays installed exactly as it was (0.5 to 1.3 GB more each).
4. Installed builds are detected automatically. The launcher starts the newest installed update of the region; with several regions installed, the region installed last (installing another region's base package again switches back to it). Every region and version has a folder of its own; there is no version to choose. Remove update returns the active region to its base game, keeping the base, saves and settings.
5. Play.

The installer stages everything next to the active installation, verifies it (identity, required archives, eboot hash, boot image) and only then swaps it in, with a backup that is put back if the swap fails. An interrupted or cancelled install leaves the installed game as it was. The packages are only read. An update package selected in Install game, or a base package in Install update, is refused before anything is unpacked.

Launcher

TRG Launcher pages: Play (install game, install update, remove update), Display, Graphics, Gameplay (text language, voice language note, skip intro, frame readouts, overlay programs), Controls (detected controllers, controller icons, keyboard bindings, port hotkeys), Trophies (kept on this PC), Bug Report, About (folders, logs, diagnostics, sponsor). There is no Online page and no Cheats page.

Renderer (Display page, also in the in-game Options menu): Vulkan is the default and the supported renderer. OpenGL and Direct3D 11 (OpenGL ES through ANGLE, Windows only) are experimental and not yet verified with this game; Auto uses Vulkan, and OpenGL when Vulkan cannot run. See docs/RENDERERS.md.

Render resolution (Graphics page, also in the in-game Options menu; applies at the next start). Render resolution (480p, 720p, Native 1080p, 1440p, 1800p, 4K) sets the size of the game's own render targets: the loader rewrites the game's 12 verified choices between 1920 × 1080 and its PS4 Pro size 3840 × 2160 (display colour and depth targets and the screen size every viewport and scene target reads), separately located in each supported executable, and above 1080p answers PS4 Pro so the game takes the path it was built to run at 4K. If a site does not hold its original instruction nothing is written and the game renders at Native, with the reason in the log. The game always shows its original 16:9 picture, with black bars where the window or display is not 16:9 (Presentation Stretch fills it instead). There is no Aspect Ratio setting and no True Ultrawide; an aspect_ratio line left in tsr.ini by an earlier build is ignored. The log's Render resolution: lines show what was requested and used.

Bug reports are sent only when you press Send report and confirm. The page builds a privacy-filtered report from one chosen log, shows exactly what would be sent, and then makes one outgoing HTTPS request to the developer's report service; My Reports shows each report's status and the developer's reply when you press Refresh. Nothing is sent at startup or in the background, there is no telemetry and no player identity, and the game is fully playable offline. When the service cannot be reached, the page says so and offers to save the same report to logs\reports\ for a GitHub issue. See docs/BUG_REPORTS.md; the service is in server/13-sentinels-bug-reports.

Port updates. The launcher checks this repository's latest GitHub release once per start and, for a newer one, shows a banner; it installs only when you choose UPDATE NOW and RESTART TO UPDATE, and not while the game is running. On Windows trg-updater.exe replaces only the port's own files after checking the package's SHA-256, and restores them if anything fails; on Linux the AppImage file is replaced by the checked new one, keeps its permissions and is started again from the same path, or put back if it cannot start. Game files, the user folder and logs are kept. See docs/RELEASE_SECURITY.md.

Languages. Text Language (menus and subtitles) is a launcher choice among the languages the installed region has: English, French, German, Italian and Spanish (USA, Europe), Japanese (Japan), Traditional and Simplified Chinese (Asia). It is kept as chosen: a language a region lacks shows that region's default and the choice stays. Voice Language is shown for information only: every build has the Japanese voices; USA and Europe 1.01 and 1.02 and Japan 1.04 ship the English ones too, and the game's own Audio Language option picks between them. Saves are kept per region (title ID); trophies are one shared list. The Japanese and Asian games can carry over a prologue demo save found in the user folder. Skip Intro answers the startup logo scene's button poll, the game's own skip. Controller icons Xbox repaints the button atlas and the icons on the built-in manual's pages in the installed archives, reversibly (scripts/prompts/README.md).

Screenshots

Linux

The AppImage runs on x86_64 Linux with glibc 2.31 or newer and a Vulkan 1.3 loader and driver. game, user and logs are kept next to the AppImage file (its own mount is read-only), or in ~/.local/share/13SentinelsAegisRimPC when that folder is not writable. Without FUSE it unpacks itself to a temporary folder and runs from there. Everything above is the same on Linux, except what only Windows has: Direct3D 11 (ANGLE) and Allow overlay programs are not offered. The file chooser is zenity or kdialog when installed, otherwise the launcher's own. See docs/LINUX.md for the full Windows/Linux comparison and what has been verified.

Building

Windows 10 1903+ with MSYS2 CLANG64:

.\tools\setup.ps1              # checks the toolchain and lists missing packages
.\tools\build.ps1              # fetches the pinned dependencies (gpu\deps.txt) and builds
.\tools\test.ps1               # focused headless tests

The output is build\cmake\clang64\bin\13_sentinels_aegis_rim.exe (launcher and game in one program) and the update helper trg-updater.exe. The PC port version has one source of truth: project(... VERSION ...) in CMakeLists.txt.

Linux (Ubuntu 20.04 prepared by packaging/linux/ci-deps.sh, the release baseline): tools/build.sh, tools/build.sh --test and tools/package-linux.sh. A release of both platforms is prepared on Windows by .\tools\package-release.ps1, which builds the AppImage in WSL2; it publishes nothing (docs/LINUX.md, docs/RELEASE_SECURITY.md).
