: Slices the image into parts for better performance in older engines.

: Beyond simple looping GIFs, exclusive tools often utilize complex Action blocks in the .def file. This allows for environmental interactions, such as floor debris that reacts to player movement or lighting that shifts during a "round win."

Before opening your tool, slice your background into logical layers using an image editor (like Photoshop or GIMP). Separate the far background (sky, distant mountains), the mid-ground (buildings, crowds), and the foreground (the floor the players stand on). Save these as PNGs. Step 2: Sprite Importing (SFF Generation)

MUGEN stages can suffer from performance drops if sprites are poorly optimized. The tool includes an exclusive indexing engine that automatically converts images to the required 8-bit (256-color) PCX or BMP formats. It matches local palettes seamlessly, preventing color bleeding or distortion when importing high-resolution assets. 3. Dynamic Bounding Box & Camera Constraints

When utilizing stage tools, you must explicitly choose your target architecture, as it drastically alters stage capabilities: WinMUGEN / 1.0 Standard Definition (typically 640x480) Full High Definition (1080p+) Camera Zooming Yes (Dynamic scaling) Color Depth 8-bit Indexed Palettes (256 colors) 32-bit True Color (PNG Alpha Channels) Stage Size Limits Restrictive memory caps Highly expanded asset scaling

Use the tool's built-in engine tester to simulate character movement. Run back and forth, execute high jumps, and test zoom parameters. Once satisfied, hit export to generate your finished .def and .sff files. Choosing Your Engine Target: MUGEN 1.0 vs. MUGEN 1.1

For years, users who struggled to hand-code stages found a reliable companion in the Stage Tool. Many creators, particularly in Spanish and Latin American forums, praised it for allowing them to build a functional stage in less than five minutes, often using it as a base to which they would later add animations and other manual tweaks. It effectively democratized stage creation.

Parallax scrolling gives 2D stages a 3D illusion of depth. It causes the floor and distant background elements to move at different speeds relative to the camera.

A normal entry looks like: stages/my_stage.def An exclusive entry might require a prefix: stages/exclusive_stage.def ; needStageTool=v2.5

Scroll to the [ExtraStages] section and add the file path for your new stage: stages/mystage.def 4. Advanced Features

: Drag-and-drop a reference character sprite to visually set the "ground" level.

The tool was initially released on Cybaster’s page on The Mugen Fighters Guild, one of the central hubs of the MUGEN community. Because it streamlined a previously complex task, it quickly became legendary in the community, and many custom stages today still owe their existence to this specific tool.
