The Incredible Crash Dummies Recompiled

The Incredible Crash Dummies Recompiled (SNES)

Shaders only work on the Vulkan and OpenGL renderers.

This project ships no game code or ROM data. You supply your own cartridge dump.

An unofficial Windows PC port of The Incredible Crash Dummies (SNES, USA), built on the snesrecomp framework from the Demon's Crest SNESRecomp v1.1.0 template. Early release (v0.1.1): it boots, plays, and has the full Options menu, but see Known limitations.

Features

• Native Windows x64 exe, built on your own PC from your own ROM.
• One-click builder: pick your ROM, it builds the game and launches it.
• In-game Options side panel (Esc / F12 / pad Guide): Video, Display, Audio, Controls, Shaders and System tabs, with a live preview and an Apply button. Keyboard, Xbox and PlayStation hint bar.
• Full shader set: the complete libretro slang preset pack (258 entries) run through librashader, plus the libretro GLSL presets. CRT, scanline, LCD, smoothing and xBR/xBRZ scalers. Shaders only work on Vulkan and OpenGL.
• 120 Hz motion option, save states (10 quick slots plus a browser), rewind, turbo, recording, fullscreen and window scaling.
• Xbox / XInput controller support with a positional SNES layout.

Play on Windows (no coding needed)

1. Download IncredibleCrashDummies-SNESRecomp-windows-x64-v0.1.1.zip from the Releases page and unzip it anywhere.
2. Open IncredibleCrashDummiesSNESRecomp.exe.
3. Click Browse For ROM and pick your own dump: Incredible Crash Dummies, The (U) [!].smc. Headered (512-byte copier header) and headerless .smc/.sfc files both work; the header is stripped before the check.
4. Let it build. The first time it downloads a portable compiler and builds the game on your PC, which takes a few minutes.
5. Click Play. Next time, just open the exe.

The zip has no game code and no ROM. It holds the setup exe, its DLLs, the shaders, the prebuilt snesrecomp-analyze.exe (so no Rust install is needed) and the build tools/configs. The first run downloads a portable toolchain (about 800 MB) into toolchain\ beside the exe and builds the game into build\; after that, opening the setup exe hands off to the built game. The zip root is flat with a single exe, so launchers such as Quiver Launcher pick it up automatically.

Shaders work on Vulkan and OpenGL renderers only. New configs default to OpenGL. On another renderer (Direct3D, software) the Shader row says so instead of applying one; switch Video > Renderer to OpenGL or Vulkan.

Controls & Shortcuts

Xbox layout. In menus, A confirms and B goes back. Esc, F12 or the pad Guide button opens the Options menu. "View" is the Xbox View/Back button, which is SNES Select.

Action	Xbox controller	Keyboard
D-pad	D-pad	Arrow keys
SNES A / B / X / Y	B / A / Y / X	X / Z / S / A
SNES L / R	LB / RB	C / V
Start / Select	Menu (Start) / View (Select)	Enter / Right Shift
Options menu (pauses the game)	Guide	F12 or Esc
Menu: move / change / confirm / back	D-pad / Left-Right / A / B	Arrows / Left-Right / Enter or Space / Backspace or Esc
Menu: previous / next tab	LB / RB	Q / E (or Tab, PgUp / PgDn)
Menu: Apply	X or Start	F5 (or the Apply button)
Save-state browser	hold View (Select) + press RB	F11
Quick load / quick save slot 1-10	-	F1-F10 / Shift+F1-F10
Rewind	hold View (Select) + press R3	Shift+F12
Open the launcher	hold View (Select) + press L3	Ctrl+L
Fullscreen	-	Alt+Enter
Reset	-	Ctrl+R
Pause / pause dimmed	-	Shift+P / P
Turbo (fast-forward)	-	Tab
Window bigger / smaller	-	Ctrl+Up / Ctrl+Down
Volume up / down	-	Keypad + / Keypad -
Show performance / toggle renderer	-	F / R
Start/stop a recording	-	Alt+R

The gameplay pad map is positional: SNES B = Xbox A, SNES Y = Xbox X, SNES A = Xbox B, SNES X = Xbox Y. The Options menu reads the pad only while it is open; gameplay input is never re-routed.

Shaders

In game: Esc / F12 / Guide, then Shaders. Left/Right picks a preset (it previews live behind the panel) and Apply keeps it. The choice is saved and defaults to Off.

• The full libretro slang-shaders preset set (258 entries: 12 audited presets first, then every preset in presets/), compiled at runtime by librashader on the Vulkan and OpenGL renderers.
• The libretro glsl-shaders .glslp presets for the OpenGL renderer.

Shaders only work on Vulkan and OpenGL. See SHADERS.md for the pinned commits and the license audit.

Tested On

The project owner's PC:

• CPU: AMD Ryzen 7 5800X3D
• GPU: NVIDIA GeForce RTX 3070 Ti (8 GB)
• RAM: 32 GB dual-channel
• Storage: NVMe SSD
• OS: Windows and AtlasOS
• Renderers: Vulkan and OpenGL

Known limitations

• Runs on the interpreter for now. No native (ahead-of-time) code is generated yet: every routine runs on the framework's interpreter tier. It plays, but it is not the fast path yet.
• No widescreen yet. It is planned.
• No battery save. The cartridge has no SRAM (the game uses passwords), so there is no in-game save to keep; use the passwords or save states. Save states come from the template and have not been fully re-tested here.
• Not played through to the end yet.

Build from source (Linux host, Windows exe)

git clone --recursive https://github.com/rac08241988/IncredibleCrashDummies-Recomp
cd IncredibleCrashDummies-Recomp
scripts/setup.sh --rom "/path/to/Incredible Crash Dummies, The (U) [!].smc"
cmake -S . -B build-win -G Ninja -DCMAKE_BUILD_TYPE=Release \
      -DCMAKE_TOOLCHAIN_FILE=$PWD/cmake/mingw-w64.cmake
cmake --build build-win -j

src/gen/ and recomp/funcs.h are generated from your ROM and are never committed.

ROM identity

File	Incredible Crash Dummies, The (U) [!].smc (headered or headerless)
Header title	INCRED. CRASH DUMMIES
Mapping	LoROM (FastROM), 1 MB, no SRAM
CRC32	0b6209ba
SHA-1	8fb4dc371c0e44fe362b23b5fec464288e3cc5ec
SHA-256	0415adfe80977485f84cdffaaa79f18c91c004c7dba202b4cf9a94eb11adeada

The hashes are of the headerless ROM; a 512-byte copier header is stripped before the check.
