This is a Nintendo Switch emulator, a direct fork of the defunct yuzu emulator rebranded as 'Citron Neo'. It provides full system emulation through high-level emulation (HLE) of Switch system services, kernel, GPU (Vulkan), audio, and input. The application has three frontends: a desktop Qt GUI, an Android app (Kotlin/JNI), and an iOS app (Swift/Metal). It supports loading Switch game formats (NSP, XCI, NCA), executing ARM code via Dynarmic, and rendering graphics via Vulkan with custom post-processing (FSR, frame interpolation). The codebase is actively developed with additions like frame skipping, a mod manager, performance overlays, and debugger tools, but retains many stub implementations from upstream, indicating incomplete feature coverage. It is primarily a desktop emulator with mobile ports.
