 - **ARMSX2** by the [ARMSX2](https://github.com/ARMSX2/ARMSX2) team (GPL-3.0) — the PlayStation 2 core, a fork of **[PCSX2](https://github.com/pcsx2/pcsx2)** (GPL-3.0), built from source into `libemucore`. PS2 online play uses PCSX2's DEV9 network adapter
 - **lsfg-vk** by [PancakeTAS](https://github.com/PancakeTAS/lsfg-vk) (GPL-3.0-or-later) — the original Vulkan reimplementation of the Lossless Scaling frame generation chain
 - **LSFG frame generation** by **Camille LaVey** of the [Eden Emulator Project](https://git.eden-emu.dev/eden-emu/eden) (GPL-3.0-or-later) — the Vulkan port of that chain that WinNative's frame generation is derived from. See [Frame generation — what came from Camille LaVey's Eden port](#frame-generation--what-came-from-camille-laveys-eden-port) below
-- **DIS optical flow frame generation** by **qwertypower** ([DEVAR Entertainment LLC](https://github.com/qwertypower)) (GPL-3.0) — a complete open-source implementation of a Dense Inverse Search frame generator, the second frame generation engine in WinNative and the one that needs no shaders from anywhere else.

 - **DIS optical flow** — the algorithm and its reference implementation come from [OpenCV](https://github.com/opencv/opencv) (`DISOpticalFlow`, [LICENSE](https://github.com/opencv/opencv/blob/5.x/LICENSE)), which adopted Till Kroeger's original [OF_DIS](https://github.com/tikroeger/OF_DIS)
 - **DXVK** by [Philip Rebohle and contributors](https://github.com/doitsujin/dxvk) (zlib/libpng) — the `dxbc` shader translator, vendored at `app/src/main/cpp/thirdparty/dxbc` to convert the frame generation shaders to SPIR-V
 - **DirectAudio** by [The412Banner](https://github.com/The412Banner/directaudio) (LGPL-2.1-or-later) — the native Wine → Android AAudio audio driver, and the only audio path in WinNative that carries a working microphone.
