nullDC SVN r36 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:
r36
Xmaple:

-. Yah, new rumble function again. Fixes Issue 96 .

PuruPuru:

-. You should now be able to map the D-Pad/Hat directions, instead of per-Hat.

-. Removed "connected" setting. Now there's an icon that shows if the port has a
PuruPuru controller connected or not.

-. Can't do a "switch to tab" but can switch tabs instead. Now when configuring
player X, the X tab will be the first one. Also, added a visual aid on the
titles to show which controller is the current one.

-. Changed default keys so now you're forced to map the controller on first
usage.

Should fix Issue 90. Hopefully. =P
