raw file

Noticed this while messing around with Sacrifice
(http://www.gog.com/en/gamecard/sacrifice).

The game stores a few keys with embedded NULLs, apparently all the ones that
store string values (dword/hex values aren't affected).

Looking at the raw registry (system.reg) shows the values fine:
"Graphic detail"=dword:00000000
"IP address"="\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"
"Key repeat delay"=dword:0000000a
"Key repeat start"=dword:00000032

but if I export the key with wine's regedit, it mangles them:
"Graphic detail"=dword:00000000
"IP address"=""Key repeat delay"=dword:0000000a
"Key repeat start"=dword:00000032

notice how a quote goes missing along with the newline. The game really likes
those newlines. If I remove them and rerun the game, then adjust its settings,
it adds them back.

I'll attach a text file with the raw registry, along with what I get when
exporting.
