nullDC SVN r81 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:
r79
look, you even seem to have a good guess what to fix XD
can you please do it?:P
I officially blame reaVer for this commit.

rec:
--A couple of workarounds, as I don't plan to fix these bugs on rec_v1x
pvr:
--Other workarounds

This commit fixes crashes, and some known dynarec glitches, by either doing
printf() instead of die or simply avoiding the codepath. This has a small
performance penalty. You can revert to the old behavior by disabling "Accurate
Mode" on the gui (or using nullDC:Dynarec.SafeMode=0). Accurate mode is by
default enabled.

Prolly i forgot some known bugs, if i remember more o them will include them on
later commits.

Fixes Issue 256 .
Hackfixes Issue 120. (pvr related)
