Getting Started
Download
Download the latest version from GitHub Releases.
Two package types are available:
- Installer (.exe) — recommended for most users, comes with proper install/uninstall
- Portable (.zip) — no installation needed
Portable Version Usage Note
Right-click the zip file → Extract All to extract all contents into a separate folder, then run SpinningMomo.exe inside it.
Do not launch SpinningMomo.exe directly inside the zip archive, and do not extract only the exe file, as missing supporting assets will cause errors.
System Requirements
WARNING
- OS: Windows 10 1903 (Build 18362) or later, 64-bit
- WebView2: Requires Microsoft WebView2 Runtime ≥ 123.0.2420.47 (modern Windows has it built-in)
First Launch
The first time you run the program, Windows may show:
- UAC prompt: Click Yes to grant admin privileges (required for resizing the game window)
Setup Wizard
On first launch, the setup wizard will walk you through:
- Pick your language and theme (dark / light / system)
- Confirm the target window title (defaults to Infinity Nikki)
Once done, the floating window will appear on your screen.
TIP
Press Ctrl + ` (backtick, top-left corner of your keyboard) to toggle the floating window anytime.
In-Game Settings
Before you start shooting, open Infinity Nikki and set:
- Display mode: Window

Your First Ultra-High-Res Portrait
- Open the in-game camera and frame your shot
- On the floating window, pick ratio 9:16 and resolution 8K (try 4K or 6K if your system struggles)
- The game window expanding beyond your screen is normal — turn on Overlay or Preview to assist framing
- Press Space to take the photo, then click Reset on the floating window to restore the window size
"Target window not found"?
Right-click the floating window (or tray icon) and re-select your target window from the menu.
