Elizabeth Figura, a Wine Developer at CodeWeavers, speaks with SE Radio host Jeremy Jung about the Wine compatibility layer and the Proton distribution. They discuss a wide range of details including system calls, what people run with Wine, how games are built differently, conformance and regression testing, native performance, emulating a CPU vs emulating system calls, the role of the Proton downstream distribution, improving Wine compatibility by patching the Linux kernel and other related projects, Wine's history and sustainment, the Crossover commercial distribution, porting games without source code, loading executables and linked libraries, the difference between user space and kernel space, poor Windows API documentation and use of private APIs, debugging compatibility issues, and contributing to the project.
