📋 About This Mod
An in-game display overlay and webapp companion for on-screen/in-game combo authoring. Modern Controls supported. Github URL https://github.com/redforth/NappuSakku/releases/tag/Nappu_Sakku_v2.25
Description
Nappu Sakku is a REFramework-based training and match HUD for Street Fighter 6 that displays live character profiles, frame data, and move detection. It includes a combo-ticker that shows up to five user-defined combos/routes per character on-screen, editable either in-game or through a companion web-app editor (served by a bundled Python Web app)
with gamepad calibration, Classic/Modern control-scheme support and backup/restore features, Frame data is sourced from D4RKONION's FAT via a PowerShell updater.
v2. 25
Automatic roster updates
The mod and web app now add new characters automatically as they release — no update/downloads/code changes required on your end. On game launch, an lua script pulls the current roster and writes it to a JSON file in reframework\data. Both server.py and index.html read that roster on startup and adjust for any new characters. (For this to work, launch the game first, then start the web app.)
Saving a combo in either the web app or the in-game editor creates the character's folder under
Street Fighter 6\reframework\data\sf6_framedata. Frame data is the one exception: because it comes from an external source, it won't populate automatically. Run NappuSakku\tools\SF6_FrameData_Updater.ps1 to pull the latest data from FAT. Barring future REFramework or D2D updates that break compatibility, the roster code shouldn't need to be touched again. New character art will be bundled with future web app updates, but you're free to drop in your own art at any time.
UI refinements
- Icons in both the web app companion and the overlay have been rearranged to flow better and look more organized.
- New overlay hotkeys
- While holding LK + MP, press:
- MK — open/close the Combo Editor
- HK — enable/disable input recording (turn it off to practice with the editor open)
- Left / Right — move the cursor back and forward
- LP — backspace in the input field
- HP — insert a spacer icon (>) in the input field
- Input icons can now be displayed in the web app. Toggle this in the overlay's in-game Display settings, or at the top of the web app page.
- Added graphic icons for 360F and 360B motions — for loyal fans.
- Added scaled PP / KK and 3×P / 3×K icons for characters whose OD moves correspond to different button strengths, and for characters like Ingrid who use three punch or kick buttons in their move sets.
