Nitrocast vs WashingtonDC

Nitrocast is a free Linux Dreamcast emulator aimed primarily at homebrew development. It began as a fork of lxdream and later became a separate project. The interface uses GTK3, and the build system is Meson. Nitrocast retains OpenGL and GTK video drivers. Developer-oriented features include mounting folders at /pc and exiting with .elf return codes. The project README describes SH4 emulation as very accurate while noting that PVR emulation is lacking. A runtime flag, --ram-size, accepts 16 or 32 to emulate the Dreamcast 32MB RAM modification. Build instructions cover cloning the GitLab repository, configuring and compiling with Meson, and running the nitrocast executable. The project was created on April 26, 2019. Its project pages provide no pricing plans beyond the listed free status, and no integrations, support terms, or security and compliance claims. It is available for Linux; no other platform is listed.

washDC, formerly known as WashingtonDC, is a free, open-source SEGA Dreamcast emulator for Linux and Microsoft Windows. It is intended for playing classic Dreamcast games on a modern x86 PC and was built from scratch rather than based on another emulator. The README lists GDI, CHD, CDI, ELF, and raw BIN game image formats, and says BIOS and flash images are required to run the emulator. Controls include keyboard input and support for up to four gamepads. Remote GDB and the WashDbg debugger are listed as TCP debugging options. Wash Emulation describes itself as a one-person team and washDC as its only product to date. The project also publishes homebrew programs for examining Dreamcast behavior, including tests of PowerVR2 backface culling and memory mirroring. Its separate gdisofs tool mounts Dreamcast game images as read-only filesystems on Linux PCs. The emulator is licensed under GNU GPL version 3.
