nullDC-Naomi SVN r66 is released. nullDC-Naomi is an open source NAOMI Arcade System Emulator. It will NOT run Dreamcast games.

nullDC-Naomi 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).
