SF2Recomp

SF2Recomp

Play as mad Titan himself against a friend over LAN, or face him again in a boss refight, with support for 4K, 120 FPS and ultrawide displays on your choosen device.

A static recompilation of Shadow Fight 2 for Nintendo Switch into a native application with offline Sparring PvP, LAN Sparring, mouse menus, remappable controls and graphics settings.

You supply the game files. No game code, assets or keys are included.

Status

Supported game input: a combined base + v1.1.0 / update v131072 NSP with its CNMT XML sidecars and tickets. Separate base/update NSPs, NSZ and other versions are not supported yet.

Platform	Status
Linux x86-64	Tested desktop development target.
Windows x86-64	Experimental; native gameplay validation pending.
macOS Apple Silicon	Experimental; native gameplay and GPU validation pending.
Android arm64 / x86-64	Development builds

Download and play

1. Download the SF2Recomp tool for your computer from Releases.
2. Extract the whole archive into a writable folder.
3. Open sf2recomp.cmd on Windows, SF2Recomp.command on macOS, or sf2recomp on Linux.
4. Enter your NSP and prod.keys paths, then choose an output folder.
5. Wait for conversion, then run sf2.exe or sf2 from the output folder.

The desktop release bundles its conversion tools and compiler. You need a compatible Vulkan 1.3 GPU and graphics driver. Windows and macOS remain experimental; successful CI checks do not establish gameplay compatibility.

Already extracted updated files work without keys through --game. Release packages are built by the desktop release workflow. If no downloadable package is available yet, use the source build guide.

Command-line conversion:

./sf2recomp --nsp "/path/game.nsp" --keys "/path/prod.keys" --output "/path/Shadow Fight 2" --play

On Windows, use sf2recomp.cmd in place of ./sf2recomp.

Android

Use the same desktop tool to build a private APK for your phone. Select Android at the prompt, or run:

./sf2recomp --android --nsp "/path/game.nsp" --keys "/path/prod.keys" --output "/path/APK" --accept-android-licenses

On first use, the extension downloads Java, SDK/NDK and build dependencies into the tool folder. It needs several GB and an internet connection. Later builds reuse these files. Android Studio is not required.

Features

Keyboard defaults: WASD to move, K/J/L/I for A/B/X/Y, and Return/Backspace for Plus/Minus. Edit sf2recomp.ini in the converted game folder for settings. Saves live under save/ by default.

Settings and controls guide · LAN guide

The recompilation adds desktop features and graphics options beyond the Switch release, and exposes some of the game's original developer tools. Settings below live in sf2recomp.ini beside the converted executable and take effect after restarting; no rebuild is needed.

Ultrawide and graphics

• Aspect ratios (experimental). [video] aspect_ratio accepts 16:10, 21:9 or 32:9, with native screen sizes of 1728×1080, 2520×1080 and 3840×1080 before uniform scaling. Restart after changing; original / 16:9 is the default. In 32:9, scenery is enlarged uniformly to cover the sides, cropping some background detail vertically. Fighter and HUD proportions are preserved. Movies keep their original proportions.

• Native display resolution. [video] internal_resolution = auto or match renders at the window's fitted drawable pixel size, following window resizing and fullscreen. Higher resolutions improve geometry edges; bitmap artwork and font atlases retain their original detail.

• Resolution scaling. Fixed internal-resolution presets of 0.25x, 0.50x, 0.75x, 1x, 2x, 3x and 4x let you trade rendering detail for performance, within the GPU's texture-size limit.

• Dynamic resolution. [video] internal_resolution = dynamic adjusts render scale in response to GPU load to work toward the configured frame-rate target.

• AMD FSR 1 upscaling. [video] upscaler = fsr1 enables spatial upscaling and sharpening when the rendered image is smaller than its window area. Use a lower internal resolution to activate it; auto selects bilinear on integrated GPUs and FSR 1 on discrete GPUs.

• SMAA anti-aliasing. [video] antialiasing = smaa enables optional post-process edge smoothing. Disabled by default.

• Configurable frame rate. [video] target_fps accepts 30–360, including targets above 60 FPS, and sets the game's target frame rate and presentation pacing. Achievable performance depends on hardware; set the host display refresh rate separately.

• Desktop window modes. A resizable window or fullscreen, selected with [video] fullscreen.

Desktop controls and menus

• Remappable keyboard and controllers. [controls.keyboard] and [controls.gamepad] map desktop inputs to Switch actions, including unbinding actions and sharing inputs.

• Mouse menus. Hover and left-click use the game's existing menu buttons. Pointer coordinates follow window resizing, black bars, HiDPI displays and configured aspect ratios; existing sliders and scroll views also receive mouse drag and wheel input.

• Menu layout. The bottom controller-hint strips are hidden on desktop and Android. Centered dialog prompts, combat hints and the gameplay HUD remain visible.

• Desktop Exit button. The main menu's localized Exit option closes the game and returns to the desktop, including in fullscreen.

• Desktop configuration. The INI also provides language selection (including system-locale detection), master volume and reverb controls. Alternate configuration and writable data locations can be selected at launch.

Sparring roster

• Unlocked Sparring roster. [gameplay] unlock_all_sparring_characters = true makes every Sparring character available without campaign progression. Enabled by default; does not change saved Story unlocks.

• Shadow and Titan in Sparring. Enabled by default with [gameplay] enable_shadow_in_sparring and enable_titan_in_sparring. Shadow uses his equipped campaign gear; Titan uses his own sword, ranged arm and magic. Move down past the third roster row to reveal more fighters at the original portrait size. See roster settings.

Boss refights and movies

• Boss refights and completed save. Defeated bosses and Gates of Shadows have a Refight button with an X shortcut, including the six boss encounters after the Gates. Refights grant no rewards and leave saves unchanged. APKs and native packages bundle a completed save, selected with [storage] use_completed_save = true. Disabled by default; uses a separate profile.

• Unlocked Extras movies. [gameplay] unlock_all_videos = true enables gallery movie playback without changing watched-video save flags. Enabled in the supplied INI.

• Intro and gameplay toggles. Skip the intro with mapped A/B, Space, or a mouse click, or disable it with [gameplay] show_intro = false. Startup data and GPU heap preparation run during playback to reduce the wait after skipping. ai_enabled and show_time_results expose the original AI and timing-display controls.

Developer tools

• Desktop developer console. Opt in with [developer] console = true; F1 or backtick opens the original console with desktop text input, command history and scrolling.

• Fight trainer and shop cheats. Optional [developer] trainer and shop_cheats expose the original fight controls and local shop actions through the console. Disabled by default; currency, items, levels and fight results can be saved by the game.

• Debug overlays. Opt in with [developer] overlays = true, then use F2 to toggle the original FPS, memory, build and model/animation displays in supported scenes.

LAN Sparring

• LAN Sparring (experimental). Native Normal/LAN and Host/Join menus, local host discovery and persistent two-player sessions. Both devices must use the same SF2Recomp release and matching roster settings. No Python launcher required. See the LAN guide.

Normal and LAN choices · Native Host and Join menu.

Android touch controls

The Android build uses the retained mobile joystick and action buttons, with simultaneous movement and attacks. Sparring characters with a special ability also get a boss-power button. Keyboard and controller input remain available. See Android development for setup and device requirements.

Saves and offline settings

• Game network blocking. [network] enabled = false is the default and blocks game connections, DNS, uploads, online multiplayer, external web links and the remote developer listener. Offline Sparring remains available. Enabling networking does not implement missing online services.

• Configurable save location and imports. [storage] save_directory selects a portable or custom save folder. Existing userdata/ backups can be imported under its save_0/ directory.

See the settings and controls guide for setup, commands and limitations, and the supplied INI for shipped defaults. Full-game stability and timing at every supported frame-rate setting remain unverified; see Status.
