nullDC SVN r27 is released. nullDC is a freeware 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:
r23
Made gpARM project.
Core is in cpu.c, recompiler in the x86 dir, needs to be ported to a assembler compatible with MSVC.
r24

r25
Fix for the behavior of the analog control and deadzone in PuruPuru and Xmaple plugins. And, made an INI setting for Xmaple's deadzone.
Also, switched L<=>R triggers for PuruPuru.
This should fix Issue 21 , hopefully. =]
r26
--nullDC is built now as a windows application instead of console :)
--nullDC/GUI now follows the nCmdShow parameter passed from windows
These, combined with -config nullDC:NoConsole=1 should make fronted integration better
Fixes Issue 40 (hopefully ?)

--Got rid of some (very) old and totally non needed code ;p
--Now also supports ""d strings for filenames in gdi toc files
Fixes issue 72
