Interesting that Ryujinx is written in C# - I'm not sure why, but at first thought I'd have expected something like a console emulator (where one would have to do "unusual" memory / GPU operations to fully match the quirks of the platform) to be written in C or C++, like Dolphin or PCSX2 (Wii / PS2 emulators) are. Though clearly they can make C# work well for it, and the benefits of working in a managed language are probably worth it.
