Jet Force Gemini Recomp v1.5.0

Jet Force Gemini Recomp 1.5.0 supports USA, PAL and Japanese (Star Twins) ROMs in one Windows x64 package, including each ROM's original in-game language options.

Download JFG-1.5.0-windows-x64.zip, extract the complete ZIP to a writable folder, open JFG-Launcher.exe, and import your own supported ROM. No first-run compilation or developer tools are required. ROMs, extracted game assets and personal saves are not included.

Highlights

• Select any loaded region from the launcher. Your selection persists across restarts; regional command-line startup and separate save storage are supported.
• Smoother Modern Aim release, corrected regional backward-walking poses, interpolated save-name keyboard buttons, and reduced excessive PAL/Japanese Vela rescue blur.
• Restored Modern-mode Arcade trap controls and Floyd objective cycling; improved night-vision and damage-tint presentation. Arcade and night-vision routes passed owner testing in all three regions.
• Optional advanced movement, free-camera, combat-transparency and actor-detail settings, plus improved cinematic, projectile and effect interpolation.
• Corrected Proton menu visibility, opening-cutscene skip delay and mouse capture, accepted on the owner's Bazzite x64 PC.
• Separate Audio Settings and About windows, stacked launcher notifications, and other launcher layout improvements.
• Choose Auto, Direct3D 12 or Vulkan under Video Settings > Rendering. Support reports now include bounded renderer-selection and presentation diagnostics.

Scope and known limits

• The Windows black-screen report in #58 remains under investigation; the renderer selector and additional diagnostics are not a confirmed fix for that report.
• #45's native NTSC behavior is reserved for a separate native-bug-fixes update. #48 remains deferred for this version.
• #57 has automated and captured-menu checks; owner visual acceptance is still pending. Bazzite PC acceptance does not establish Steam Deck or every Proton configuration.
• Broader campaign coverage and exact original-game timing retain their documented limits. Original native bugs are preserved unless explicitly documented otherwise.

Built from clean source commit 1e2ba830b871aa3d9a80064a7fe59c579641b461 for the launcher and all three regional runtimes. The inventory and SHA-256 files accompany the ZIP; the release workflow verifies the package and runs the required source checks before publication.

Jet Force Gemini Recomp v1.4.0

Jet Force Gemini Recomp v1.4.0

This update adds in-game cutscene skipping and improves controls, effects, camera behavior and launcher tools.

• Press A, B or Start during supported cinematics to reveal the prompt, then hold A for one second to skip. Native scene completion preserves progression; some skips still take time to finish.
• Independent Modern controls for P1-P4, expanded Floyd controls, native boss aim limits, and crouch/prone side rolls with optional bindings.
• Camera fixes for landing, ledges, swimming and returning from the map or another window.
• Rain and weapon-reticle fixes during normal Play, plus rain during supported room-entry fades.
• Improved Tawfret sky/fog, Quarry day/night transitions and tribal brightness.
• Correct cinematic camera cuts and remove the original game's visible camera-helper square in the Tawfret chief sequence.
• Fix Give weapons while Mods pauses the game, keep removed controllers unassigned, and improve launcher feedback and menus.
• Add a fallback for unavailable DirectComposition. Steam Deck/Proton still needs reporter verification.

Extract the complete ZIP, open JFG-Launcher.exe, and import a supported North American ROM. No ROM, original game assets, personal saves or debug symbols are included.

Remaining reporter-specific mouse, audio and performance reports are documented in known issues. This update does not claim those unresolved reports are fixed.

Jet Force Gemini Recomp v1.3.0

Download JFG-1.3.0-windows-x64.zip, extract the complete ZIP, and open JFG-Launcher.exe. Import your own supported North American ROM once. No compiler or WSL is needed; no ROM or extracted game assets are included.

What's changed

• Smoother cutscene and boss presentation, with high-resolution blur composition and improved interpolation.
• Off / Reduced / Original motion blur, with Reduced as the default.
• Corrections for shaking glass and grounded drone bodies.
• Mouse camera retention after high landings and ledge climbs, plus native standing-aim movement speeds.
• Game > Settings > Change directory for movable saves, settings and imported ROM storage.
• Tabbed Video Settings, updated window chrome, and live 0–100% fog strength.
• Explicit map exit warps bypass progression gates; Give all weapons is available under Map > Settings > Mods.
• Existing v1.2.1 boss-controls fixes are retained.

The owner completed the New Game-through-Vela route and targeted visual checks. The final long capture recorded zero audio underruns/overruns. Broader hardware/scene coverage and reporter-specific invasion-replay, Ally X and Linux AppImage findings still need retesting; this is not a universal zero-stall claim.

For a portable installation, retain your selected data folder and storage-location.txt when updating or moving the game.

Jet Force Gemini Recomp v1.2.1

1.2.1 hotfix

• Fixed modern controls losing movement, strafing and independent mouse/controller aiming in boss fights. Owner playtests passed Vela/Ichor, Juno and Lupus.
• Fixed map exit warps stopping at the door instead of entering the next room. Native progression requirements still apply.
• Fixed the scene FPS counter double-counting the extra full-screen motion-blur pass. Output FPS is measured separately.

This is a focused controls/tools hotfix. Cutscene and boss blur, presentation stutter and remaining audio interruptions are tracked in #21 for 1.3 alongside the ongoing general performance improvements.

Download the Windows x64 ZIP and extract it into a new folder. Run JFG-Launcher.exe and import your own supported North American ROM if prompted. Existing profile saves/settings are retained. No compiler or WSL is required.

The checksum and package inventory accompany the ZIP. The playable runtime is the exact clean binary used for the accepted boss tests; its original source identity is retained. The stable launcher/package is built from the tagged main revision.

Jet Force Gemini Recomp 1.2.0

Download JFG-1.2.0-windows-x64.zip, extract the complete ZIP to a new folder, and open JFG-Launcher.exe. Existing saves and settings remain in your profile. Supply your own supported North American ROM; no compiler or WSL is required.

• Smooth high-refresh rendering with VSync, Custom FPS and Unlimited, preserving game timing.
• Improved combat performance, audio sample delivery, camera/character/scenery interpolation and bridge rendering.
• Full Modern Controls editor, mouse look, dual-stick aiming, shared keys and visible menu/dialogue bindings.
• Fixes for the reproduced mouse/keyboard startup crash, disappearing shuriken reticle, resting-shuriken jitter and crouch mouse inversion.
• Amber GitHub update banner below Play. What's new opens the project page; Update now opens the release/download page. Updates are never installed automatically.
• Portable GCC source fixes and clearer legacy firmware/WSL setup diagnostics.

This is a Windows x64 package. Modern gameplay and high-refresh rendering remain opt-in. Unlimited pacing, exhaustive no-dip coverage, shadow cadence and the reported Goldwood exit-cutscene audio hitch retain their documented limits. A Linux AppImage and fresh Windows 10 source-install qualification are not part of this package.

The release candidate passed all required CI jobs, GCC and Clang Linux host tests, 84 local sanitizer tests, Windows game/input tests, 642 managed launcher checks, 790 native controls checks, 78 update UI checks and 28 setup checks. Muted clean-build startup and normal Play completed with zero reported audio underruns. Tests have finite scope; this is not a claim of exhaustive hardware or campaign performance coverage.

Jet Force Gemini Recomp v1.1.0

Download JFG-1.1.0-windows-x64.zip, extract the entire ZIP, and open JFG-Launcher.exe. This is the playable Windows x64 bundle, including the game runtime and required libraries.

• Restored a centered 4:3 game area, preserving cutscene bars in wide windows and fullscreen.
• Added one-time ROM import. After a successful import, the original ROM file can be moved or deleted; play uses the local copy.
• Removed the central ROM banner after import. Game > Select ROM... remains available.
• Removed the need for Git, Python, Visual Studio Build Tools, WSL, and a first-run build.
• Added a clear hardware-graphics requirement message for software-only VMs.

Existing saves and settings remain in your profile. No ROMs or game assets are included. Import your own supported North American .z64 ROM. The simplified installation approach was inspired by the Zelda64Recomp team; see the README for credit.

JFG Launcher 0.4.0-preview.4

JFG Launcher 0.4.0-preview.4

Graphics completion now follows the original game's yield request during
the Vela unlock sequence. Audio continues playing while buffered samples
remain, removing the avoidable pause observed in that scene. Recycled
renderer memory is refreshed for CPU textures, fixing the recorded opaque
water-splash rectangle.

Changes

• Correct pending graphics completion timing during audio scheduling.
• Keep nonempty audio queues playing while retaining startup buffering and
  recovery after a genuine underrun.
• Restore particle transparency after framebuffer memory is reused.
• Allow longer input recordings and preserve bounded replay parsing.
• Add an opt-in Juno double-run-speed mod setting. Normal gameplay is unchanged.

Existing volume/mute controls, crash reports, controller mappings, shadows,
live map/inventory and experimental navigation remain available.

Playtest progress

Maintainer-reported progress: Juno reached Mizar's Palace after Tawfret;
Vela was tested up to Cerulean; Lupus progress has not yet been reported.
These sessions used health/enemy-clearing mods. They demonstrate traversal
coverage, not complete unmodified campaign or original-console accuracy.

Validation and remaining checks

• Eight focused native renderer, scheduler, audio/graphics bridge, replay,
  playback-buffer and mod tests passed.
• Two 30,642-VI particle replays completed normally. The matching comparison
  retained identical final CPU memory while restoring splash transparency.
• The current native runtime was rebuilt with both timing and particle fixes.
• The earlier real-time Vela sequence replay recorded no audio underruns or
  interior audio pauses; audible confirmation still needs a playtest.
• The maintainer confirms all previously reported broken particle effects now
  render correctly: splash, dust, pickup sparkles, ship exhaust and Tawfret rain.
  Juno water effects remain untested.
• One prior run failed in DirectX shader compilation near a Windows desktop
  compositor failure. Monitored reruns succeeded; its cause remains unconfirmed.
• Windows 10 setup limitations and experimental navigation restrictions remain
  as described in known issues.

Install

Use your supported US big-endian ROM. Select Set up and build again to
build this launcher's pinned source revision, then launch with your existing
save profile. The package contains the launcher, setup guides and license.
It does not contain a ROM, game assets or a generated game executable.

JFG Launcher 0.4.0-preview.3

Windows x64 playtest preview. Supply your own supported North American ROM; the launcher builds the game locally.

• Live volume and mute controls.
• Restored original CPU processing of the player shadow mask.
• Sound-player clock recovery after queue overflow.
• Optional live map with height layers, collision geometry, exits, items, chests, NPC rewards and Mizar token dots.
• Optional inventory window with Juno, Vela and Lupus tabs.
• Experimental Navigation mod now shares walking, calibrated jump chains, dialogue and destination execution across supported NPC rewards, chests, keys and exits.
• Corrected shader header rebuild dependencies, following lukedeardoff's report.

Download JFG-Launcher.exe or the ZIP with the same launcher, guides and license. Close the old launcher before upgrading. Rebuild an older game with Set up and build to gain the native fixes; keep your existing save profile. Leave Navigation mod off for normal play.

Automation remains experimental: the latest stair/NPC sequence has recorded-geometry and simulated-command validation, not a completed native traversal. Full campaign completion, original-console accuracy and a pristine Windows installation remain unverified. Windows 10 setup still has known issues. Lupus hover, moving platforms and unsupported scripted gates require manual play.

Only the launcher, documentation and license are distributed. No ROM, game assets, generated game executable, runtime DLLs, saves or debug symbols are included. HD cosmetic variants remain community-maintained.

JFG Launcher 0.4.0-preview.2

Windows x64 playtest preview. Use your supported North American big-endian ROM to build the game locally.

• Choose the affected support session; failed sessions survive later successful launches.
• Reports include filtered setup/compiler errors, Windows/GPU driver details, controller settings, game-build identity and recent runtime progress.
• Rebuilt games record best-effort crash stacks and support Capture freeze while running. Shared ZIPs contain text stack locations, not raw game memory.
• Windows builds use short per-checkout cache paths. Dependency downloads enable Git long paths and retry incomplete submodule initialization.

Download JFG-Launcher.exe, or the ZIP with the same launcher, guides and license. Close the old launcher before upgrading. Rebuild your game with Set up and build to gain native crash/freeze capture; saves stay in your existing profile. No automatic diagnostic upload occurs.

Windows 10 setup still needs work on firmware-virtualization detection, older WSL installations, and PowerShell prerequisite probes. A pristine Windows/UAC/reboot installation and full campaign completion remain unverified. See the known issues.

Only the launcher, documentation and license are distributed. No ROM, game assets, generated game executable, runtime DLLs, saves or debug symbols are included.
