Minimum

OS:
Windows 10, Windows 11; Linux 6.6 (Older LTS), Ubuntu 22.04 or later; macOS 15 or later; FreeBSD 14.4 or later
Processor:
Any x64 CPU, AMD or Intel; CPUs without AVX2 or with 4 threads or less should perform badly, as should AMD CPUs with 2 cores per CCX
Memory:
8 GB of RAM or more; single-channel memory should perform badly
Graphics:
AMD: OpenGL 4.3 or newer running on Linux, TeraScale architecture (HD 2000 series) or newer; NVIDIA: OpenGL 4.3 or newer, Fermi architecture (GTX 400 series) or newer; Intel: Vulkan 1.2 or newer, Alchemist architecture (A series) or newer
Storage:
SSD or HDD storage for emulator data and games: 512 MB for base emulator data, 128 MB for emulator cache and console user data per installed game, plus a highly variable dev_hdd1 virtual console cache per installed game
Notes:
For being able to boot/run games, performance is not guaranteed.

Recommended

OS:
Windows 11 25H2 or later; Linux with latest stable or latest LTS kernel; macOS 15 or later; FreeBSD 14.4+, 15.0+ or later
Processor:
AMD: 6 cores and 12 threads or more, Zen 3 architecture or newer; Intel: 6 cores and 12 threads, 8 cores or more, Comet Lake architecture or newer
Memory:
16 GB of dual-channel RAM or more; memory in dual-channel mode is highly recommended over single-channel
Graphics:
Vulkan 1.2 compatible with active driver support — AMD: RDNA architecture (RX 5000 series) or newer; NVIDIA: Turing architecture (RTX 2000 series) or newer; Intel: not recommended, Intel GPUs and drivers are currently unsupported
Storage:
SSD storage for emulator data, SSD or HDD storage for games: 512 MB for base emulator data, 128 MB for emulator cache and console user data per installed game, plus a highly variable dev_hdd1 virtual console cache per installed game
Notes:
For running all playable games with playable performance.

Hardware requirements vary depending on your configuration; the project guarantees no good performance below the recommended tier.
