![]() ![]() 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.
