nullDC 2.0.0
What it is
nullDC 2.0.0 is a Sega Dreamcast emulator with browser use and downloadable builds for Windows, macOS, and Linux. The browser page provides a WASM embed where users can drop files to start the emulator. One startup option requires the Dreamcast BIOS files dc_boot.bin (2MB) and dc_flash.bin (128KB); the other uses an .elf executable. The project describes accuracy as an aim. The builds page lists v2.0.0-pre-388-g95a924b as its most recent build, dated 2025-11-10 08:17:38 UTC. Listed downloads include aarch64 and x86_64 builds for Windows and macOS, and aarch64, riscv64gc, and x86_64 builds for Linux. The project is open source under the MIT license, which provides the software without warranty. The home page also retains older beta releases, including beta 1.6 from 2007 and a stereoscopy build from 2008. Its historical beta 1 netplay server is compatible only with beta 1. The project points users to the nullDC forum at ngemu.com for help.
