+Windows users should note that only Windows 10 v1803 or newer is supported because of the [Fastmem technology](https://yuzu-emu.org/entry/yuzu-fastmem/). However, the emulator might still work for older systems like Windows 7 when Fastmem is disabled. In Windows, Fastmem is disabled by default if the emulator fails to allocate 4GB of memory.
