CheezyEmu

CheezyEmu is an experimental, open-source Nintendo Switch and Switch 2 emulator written in C++, tuned for AMD graphics cards: AMD performance fixes, saved compiled shaders, AMD FSR 4 and AMD frame generation. It runs on NVIDIA and Intel GPUs too.

README.txt (also next to cheezyemu.exe in every download) explains shader packs, the switches file, FSR and frame generation. CHEEZYEMU.md lists every change and its credits.

New in build 10

• FSR presets for Ocarina: Native AA, Quality, Balanced, Performance, Ultra Performance.
• Fog no longer turns solid white (Hyrule Field drawbridge, Kokiri Forest).
• No more stale or glowing geometry from old vertex data (Hyrule Field, the graveyard).
• FSR 4 that draws a black picture switches itself to FSR 3.1 instead.
• Less memory used when shaders precache, faster NUP loading.
• A missing or broken microphone no longer breaks games.
• In-app updates retry when GitHub has a hiccup.
• Now its own emulator: CheezyEmu, with a new name, icon and look.
• Future updates install from inside the emulator: no more downloading each build.

CheezyEmu is not affiliated with Nintendo.

Downloads and setup

Download CheezyEmu only from this repository's releases page.

On Windows, extract the entire build archive and run cheezyemu.exe. Only use games and system files you have legally obtained. Games, keys and firmware are not included.

Existing saves and settings

CheezyEmu uses the same data folders as the emulators it builds on (Eden/Eglantine), so saves, settings and shader caches carry over. Back up your saves before testing experimental builds.

Reporting a problem

Post in the Discord or open an issue, and include:

• The exact build, game version, CPU, GPU and driver version.
• Relevant settings and steps to reproduce the problem.
• A screenshot and the log from the affected session, after checking it for personal information.
• For a crash, the cheezyemu.exe.*.dmp file and which zip you used (standard or PGO).

Do not upload game files, keys, firmware or private account information.

Building and contributing

See the build guide, user documentation and coding guidelines. Some inherited documentation and internal build target names still use upstream names. The GUI build target remains yuzu; its output is cheezyemu.exe on Windows and cheezyemu on other desktop platforms.
