All you have to do is add the directory where you stored the games you'd like to play to the application, and Redream will detect these executables and play them. This is a great way to relive your past and get the full experience of gaming on the Dreamcast.
In version 1.2.3, inolen made a major change to the audio/video synchronization of redream. The MultiSync feature helps prevent ear-piercing crackling and unexpected latency, as well as skipped frames in video output. This change requires some additional code complexity and memory bandwidth, but it is worth it for those who have lower-spec machines. It also keeps the main thread running without being interrupted by vsync, which is a major drawback with older machines.
