3DSnickerStream v2.6 adds Upscaling Filters — sharpen and clean up the little 3DS picture on
your big screen, in real time on the GPU. 🔍
The 3DS screen is tiny (400×240); stretched to a monitor it gets blurry or jagged. These filters fix
that — from a light sharpen to true edge-directed pixel-art upscalers to a neural network. Pick one from
the new Upscale dropdown in the stream bar.
The filters
| Filter | Best for |
|---|---|
| Sharp | crisp, hard pixels — a fast general sharpen |
| xBR | 2D pixel art — smooth, clean diagonals (the classic emulator look) |
| Super-xBR | 2D pixel art — like xBR but anti-aliased edges |
| ScaleFX | 2D pixel art — the reference edge-interpolation upscaler; the smoothest of all |
| FSR | 3D games — AMD-style edge-adaptive upscale + sharpen |
| Anime4K | cel-shaded / line art — smooth base + strong line sharpening |
| Anime4K CNN | a real neural-network upscaler running live on the GPU |
pixel-art tip: xBR / Super-xBR / ScaleFX shine on clean edges — pair them with a Lossless
compression mode for the best result. For 3D games, FSR is the pick.
How it works
Everything runs on your PC's GPU (the stream still comes from the 3DS as before). The filters are
faithful ports of well-known GPU shaders to Avalonia's Skia engine — no external dependencies, still a
single portable download. The multi-pass filters (ScaleFX, Anime4K CNN) chain several shader passes
through GPU textures; if your machine has no GPU, they gracefully fall back to a CPU path.
Downloads
| Platform | File | Notes |
|---|---|---|
| Windows | …-win-x64.zip |
unzip, run 3DSnickerStream.exe |
| Linux | …-linux-x86_64.AppImage / …-linux-x64.tar.gz |
chmod +x the AppImage, or extract the tarball and run ./3DSnickerStream |
| macOS (Apple Silicon / Intel) | build locally | a few minutes with the .NET SDK — no Gatekeeper hassle |
The CI ships Windows + Linux; the macOS build is produced locally — see
