Unicorn

Unicorn is a CPU simulator with bindings in many languages, including C#/.NET. It is used by the Ryujinx test suite for comparative testing with its built-in CPU simulator, Armeilleure.

Windows

On Windows, Unicorn is shipped as a pre-compiled dynamic library (.dll), licenced under the GPLv2.

The source code for windows/unicorn.dll is available at: https://github.com/MerryMage/UnicornDotNet/tree/299451c02d9c810d2feca51f5e9cb6d8b2f38960

Linux

On Linux, you will first need to download Unicorn from https://github.com/unicorn-engine/unicorn.

Then you need to patch it to expose the FSPCR register by applying linux/unicorn_fspcr.patch

Then, compile Unicorn from source with its make.sh script.

See https://github.com/Ryujinx/Ryujinx/pull/1433 for details.
