Dolphin vs QEMU

Dolphin is free, open-source software that emulates Nintendo GameCube and Wii consoles so users can play games for those systems on a PC. It also runs on Android, Linux, macOS, and Windows, and requires a 64-bit operating system. Listed enhancements include full HD (1080p), PC controller compatibility, turbo speed, and networked multiplayer. The FAQ describes compatibility as high across most GameCube and Wii titles, while warning that some games can have defects, errors, or crashes. Dolphin uses the GPLv2+ license; distributing it requires releasing source code and providing attribution. Downloads include Windows x64 and ARM64, macOS for ARM and Intel, Android, and Linux Flatpak packages. Stable releases are made every few months, while development versions appear several times a day and are less tested. The FAQ recommends at least 2 GB of RAM and notes the importance of GPU support for DirectX 11.1 and OpenGL 4.4. Community resources include Discord, forums, a wiki, and GitHub; bug reports go to the issue tracker. Dolphin states that it is not affiliated with Nintendo.

QEMU is a free, open-source machine emulator and virtualizer. System emulation models an entire machine, including its CPU, memory and devices, so it can run a guest operating system. User-mode emulation runs processes built for one CPU architecture on another. The package also includes qemu-img, a command-line utility for creating, converting and modifying disk images. QEMU can work with KVM, Xen and Hypervisor.Framework so guests can run directly on the host CPU. Supported build platforms include Linux, macOS, FreeBSD, NetBSD, OpenBSD and Windows. Windows support is limited to 64-bit, while macOS requires the newest version currently available; support for the prior version is eventually dropped. For complex networking and storage configurations, the project recommends management tools such as virt-manager. Its security guidance distinguishes virtualization with an accelerator and listed machine type from TCG non-virtualization use, which does not provide guest-isolation or security guarantees. QEMU is released under GNU GPL version 2, with some components under specific licenses.
