nullDC-Naomi SVN r43 is released. nullDC-Naomi is an open source NAOMI Arcade System Emulator. It will NOT run Dreamcast games.

nullDC-Naomi SVN Changelog:
r43
PuruPuru:

-. Now supports input from Keyboard. (and mouse buttons too)

Yup, you can now mix Joystick and Keyboard.

Also, since r41 "Half Press" affects not only Triggers but Main Stick too. That helps those using digital input as main stick get a half movement. In that case however, be sure to keep the deadzone at minimum.
