Windows CE Dreamcast Community Edition (wince-dc) is an open-source project that transforms the stripped-down Windows CE 2.12 runtime bundled with Sega Dreamcast game discs into a fully usable multitasking windowed desktop environment. It features a custom shell (DCWin) with windows, taskbar, Start menu, and mouse cursor rendered via the Dreamcast's PVR2/Direct3D hardware, plus built-in apps (Explorer, Task Manager, Clock, Calculator) each running as separate CE processes. An in-progress TCP/IP networking stack over the Broadband Adapter or W5500/SPI is also included. The entire toolchain — including the SH-4 PE compiler and CE image tools — is vendored in the repo, so a single CMake/Ninja invocation produces a bootable GDI disc image with no external SDK or Platform Builder required. Build options allow switching between retail/debug kernels, custom autorun binaries, and injecting extra disc content.
