v0.1.0-preview.1 — Linux release

First public Linux x86-64 release of Last Raven Recomp, including support for Armored Core 3 Portable and Silent Line Portable.

Download and play

Download Armored-Core-Portable-x86_64.AppImage, mark it executable, and open it. On Steam Deck, do the first setup in Desktop Mode.

1. Choose Add Game and select your own supported PSP ISO.
2. Keep the launcher open while it prepares the game locally, then choose Save & Play.
3. For Steam Deck Gaming Mode, add the AppImage as a non-Steam game. Leave Proton compatibility overrides off.

If FUSE is unavailable, run ./Armored-Core-Portable-x86_64.AppImage --appimage-extract-and-run.

The download includes the compiler, Python runtime, SDL, font and media libraries. It contains no game executable, generated game code, game assets or saves. Keep your ISO accessible after preparation; the game reads assets from it. Preparation needs at least 2 GB of free library space.

Supported US PSN version	Disc ID	Version
Armored Core 3 Portable	NPUH10023	1.01
Armored Core: Silent Line Portable	NPUH10025	1.00
Armored Core: Last Raven Portable	NPUH10024	1.00

Included

• Native Linux launcher with ISO import, saved settings and per-game preparation.
• Modern controller and keyboard/mouse controls, adaptive widescreen and native-resolution rendering.
• Optional Higher FPS mission rendering for all three titles. Start with a 60 FPS cap; simulation remains at its original cadence. Menus, movies and some effects retain their original cadence.
• Interactive save/load/delete dialogs and shared per-title save folders for source and packaged builds.
• Steam Input controller handling, plus normal shutdown with View + Menu held for two seconds or Ctrl+Shift+Q. Save in-game before quitting.

Updating from a private test build may require Prepare Game once per affected title. Existing ISO locations, presets and saves are retained. Saves normally live under ~/.local/share/last-raven/saves/.

Scope and verification

This package targets Linux x86-64 with glibc 2.35 or newer. There is no Windows or macOS binary in this release. The maintainer has confirmed that this release works on Steam Deck.

Validation passed: 9 package tests, 13 importer tests and 10 fingerprint tests; settings, launcher, save-dialog, FPS and presentation fixtures; AppImage extraction/startup; source, checksum, dependency and ELF audits. All three games were freshly prepared with bundled tools from a read-only extracted AppImage. Their stock, 60 FPS and 90 FPS replay control logs matched with zero bad guest memory accesses. A 1280×800 desktop OpenGL Last Raven replay through the packaged launch path also completed with the saved 60 FPS preset, matching the stock control log and reporting zero bad accesses. These automated results were collected on a development PC; Steam Deck operation was subsequently confirmed by the maintainer.

Built from Last Raven 56686c1 and psprecomp d6d699d. RELEASE.json records build-time provenance and validation; BUILD.json records source hashes, dependency pins and the ELF audit. SHA256SUMS covers the attached release files.
