This repository contains the original source updated to SDL 2.0 from SDL 1.2, as well as some cross platform enhancements (removed MFC/ATL dependency on Windows, use dearImGui on all platforms, built in shader editor for post-process effects). The sound emulation has also been updated to fix a bug in the noise channel, as well as tighten the cycle timing relative to the CPU emulation, which vastly improves (imo) the quality of the audio sync with the video.
