nullDC SVN r65 is released. nullDC is an open source Sega Dreamcast(DC) and NAOMI videogame systems emulator for Microsoft Windows. nullDC runs several Dreamcast games at good speed, with full sound and music. NullDC requires the latest version of Microsoft DirectX, the latest Visual C++ runtime libraries and optionally WinPcap for modem emulation. As usual for emulators, a dump of the original console BIOS is also needed. It has a plugin architecture, with several alternative implementations (some ported from Chankast) for graphics, sound, reading games burned to CD-ROMs (it cannot read GD-ROMs directly) or disk image files, memory cards, etc.
