nullDC-Naomi SVN r127 is released. nullDC-Naomi is an open source NAOMI Arcade System Emulator. It will NOT run Dreamcast games.

nullDC-Naomi SVN Changelog:
r127
Xmaple:
-. PuruPuru Pack (rumble) device now has SDL support. Fixes Issue 8.
-. Updated SDL.DLL to v1.3.0 which has Haptic (rumble) support. Fixes 133.

Therefore, SDL 1.3.0 is now required to compile. To enable SDL rumble, edit SDL_Rumble on the Config.INI file since Xmaple still has no GUI. Also, RealFrequency ain't working with SDL.
