Switch yuzu5/20/2023 ![]() ![]() This was helpful for getting the system up and running in the early days. yuzu uses unicorn as the fallback implementation. ![]() 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. I started working on an AArch64 (ARMv8) frontend for dynarmic upon request from yuzu's developers.
