nullDC SVN r66 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.

nullDC SVN Changelog:
r66
Fixed a buffer overrun (and a potential second one) on the .cdi handling routine
on image reader. The image reader still needs a rewrite however...
Adjusted the drive state after SPI command 71 even more. Hopefully it will be
good enough to keep every software happy now (and until a more appropriate
implementation is done when more info about it becomes available).
