We use this version of unicorn to test dynarmic by fuzzing the emulators against each other to ensure accuracy of emulation.ĭynarmic has 'fallback' capability - if an instruction isn't implemented, a user-provided callback is called so the library user can provide an implementation of the unimplemented instruction. When I last looked at unicorn it didn't quite have a full ARMv8 implementation yuzu maintains a fork of unicorn that follows upstream qemu more closely at. Dynarmic has different goals: (a) performance and (b) ease of integration into pre-existing/custom emulated memory systems. To be honest, I feel like unicorn has instrumentation as a primary goal. At the time, they decided to switch over because dynarmic has better performance compared to unicorn.

This particular emulator aims to help developers learn the Switch hardware and software stack, aiding in homebrew app development for the console.I started working on an AArch64 (ARMv8) frontend for dynarmic upon request from yuzu's developers. While some might see the value in PC emulators making playable games, a lot of these are made for game developers to use for research and reference, or even their own rebuilds and ports of games. The emulator is able to 'boot some games, to varying degrees of success, but does not implement any of the necessary GPU features to render 3D graphics,' per the website. The yuzu can't play Switch games, and while it may take a while to go live, the team calls Switch game emulation a 'top priority' of theirs.

This effort, still in its early stages of development, doesn't quite have that kind of approval or notice just yet. Just weeks ago, we reported on an emulator project that was on the verge of working with Nintendo in an effort to emulate PC games on the Nintendo Switch. Announcing yuzu, the first Nintendo Switch emulator that does all of the things you didn't need it to do! Stay tuned for more from the yuzu team!
