0.1.0-alpha.4

The fourth Windows x64 alpha brings wider menus, smoother mouse turning, keyboard save naming, replay capsules, and improvements to the launcher and renderer.

Changes since alpha.3

• Widescreen menus and fixes. Front-end menus fill a wide screen while the logo and text keep their shape. Loading screens, pause-menu text, and the ordering of world sprites have been corrected.
• Keyboard save names. Type letters, digits, and spaces on the game's save-name screen. Backspace and Delete edit the name; Enter moves to DONE.
• Smooth mouse turning. An optional setting in Controls turns the picture between the game's 256 heading steps. It requires captured mouse aim and exact geometry.
• Renderer options. Gap filling closes small gaps between polygons. Optional depth sorting changes how world polygons overlap, and experimental ambient occlusion adds adjustable shading in corners and under objects. These options require exact geometry.
• Replay capsules and reporting tools. Ctrl+F12 starts and finishes a capsule containing a save state, input, settings, and build details. The new Debug tab offers diagnostic views and a short screen recording for rendering reports. Capsules require the build that recorded them and are not recorded in network games; see the replay instructions for playback and its limits.
• Launcher improvements. Long settings pages scroll, hovering over an option shows its explanation, and experimental renderer options are available before starting the game. Play restores settings omitted from an older settings file. Paths containing non-ASCII characters are handled correctly.
• Window and state fixes. Borderless fullscreen stays borderless on Windows, mouse capture returns when the window regains focus, and loaded states resume with their saved CPU timing settings, including in headless mode.
• Language and settings layout. The in-game language controls have their own tab. Long explanatory notes wrap, and the 60 FPS and in-between-frame options have clearer labels.

Thanks to Solganis for the contributions in #16–#35.

Getting started

1. Download DisruptorRecomp-v0.1.0-alpha.4-win64.zip below and use Extract All.
2. On Windows 10/11 x64, install the Microsoft Visual C++ x64 Redistributable if needed. Your GPU driver must support OpenGL 3.3. The launcher itself does not require that redistributable.
3. Open DisruptorLauncher.exe and browse to your own supported Disruptor USA (SLUS-00224) raw MODE2/2352 BIN/CUE. The launcher imports and verifies it. An identical raw ISO/IMG is accepted; cooked 2048-byte ISOs are unsupported.
4. Select Play game, then use arrow keys and Enter at the game menu. Play Disruptor.cmd opens the same launcher.

OpenBIOS and dependency licenses are included. Game data and language discs are not included. No build tools, extracted game executable, or proprietary BIOS are required. French, German, and Japanese language content can come from an additional owned disc; the supported USA disc remains required.

Updating

Extract into a fresh folder and back up saves/ before updating. Copy your memory-card saves and settings.toml if desired. Copying input/discs/ from an existing launcher installation avoids another import; the launcher verifies it before booting.

Use the game's memory-card saves for progress across releases. Save states and replay capsules are specific to their build and language; compatibility across releases is not guaranteed. States from alpha.1 and alpha.2 remain incompatible with alpha.3 and later.

Defaults are 4x resolution at 4:3 with modern controls, geometry correction, and perspective textures. Vertical look, smooth mouse turning, 60 FPS gameplay, in-between frames, depth sorting, ambient occlusion, and intro skipping start off. Movies, maps, and loading screens remain at 4:3.

Validation and known limits

The Windows x64 Release build, code-generation audit, and all 77 automated checks passed. The ZIP's exact 23-file list, x64 executables, source commit, manifest hashes, and download checksum were checked. Its packaged launcher imported and verified a real supported USA disc dump, and the packaged runtime passed a 12-second headless startup check.

This validates the build, installation, and booting. Full campaign coverage and broader live testing of the new renderer options remain incomplete. Minor geometry or texture artifacts can remain. Regional language handling has automated fixture coverage; broader testing with real regional images is still needed.

Read GETTING_STARTED.md in the ZIP or the player guide. Report issues with the level, reproduction steps, settings, and startup.log; do not attach game data or BIOS files. The .zip.sha256 asset contains the download checksum.
