I understand that the Intel processors (and probably every other
Intel-compatible processor around) has a special register bit that can
be set, something related to debugging? With debugging, you're running
the app "under" another app that is monitoring what is going on and can
stop the app being debugged. Maybe part of the copy protection is
checking that bit, to avoid someone reverse engineering the game by
running it under a debugger? And maybe WINE is functioning the same way?
(Sorry, don't ask me, the last time I spent programming any chip at
machine code level was with the 6510 processor in my old Commodore 64!)

G'day,
I'm using a cvs version from a few days ago, and I've just installed The
Sims and its Livin' Large and House Party extensions with minimal
fuss (the
icons were missing in the first setup/autorun screens).
Trying to run the program, it displays a dialog with the title "A
debugger
has been detected" and the text "Unload the debugger and try again".
So, how can I disable/hide the debugger?
IIRC, the "debugger" that the program is reporting is WINE itself. Now
WHY that is happening, someone who knows WINE will have to explain.
The short version is that Wine is not able to fool all copy protection
schemes in existence (as yet).
Basically, the game's copy protection is looking to confirm the
legitimacy of the game CD, but some of them apparently do this by
confirming the legitimacy of Windows in some way as well (I'm not a
programmer, so I don't know any further technical details; this is what
I've gleaned from observation and eavesdropping on people who do know
further technical details). Since Wine does not always succeed in
convincing the copy protection that it is in fact Windows (not
surprising, since it isn't), the copy protection does what it was
designed to do and refuses to run the game.
However, since what is perceived as illegitimate is Windows, not the
game-- and the game is what really concerns the makers, after all-- you
get a "second chance" via a friendly warning to "stop the debugger" (or
whatever else is causing Windows to be percieved as something other than
"normal" Windows), and try again.
This is why a no-cd crack usually solves the problem; they are designed
to disable the copy protection entirely, which in this case works in our
favor, as annoying as it is to have to use a crack on a store-bought
retail game.
