WINEDEBUG=+all,-relay wine FGP.exe

Hi!

I'm trying to get the game Flåklypa Grand Prix to run in Wine, but it is
proving more difficult than I would like. The game uses CD-COPS DRM, and when
it tries to validate the CD it fails.
> From what I can see, the copy protection uses some 16 bit commands. And it is

at this point it fails.

The execution path is as follows:
Start FGP.exe
- Unpacks CD-COPS files to TMP
- Starts UC16.exe (with some unknown parameters)
- UC16.exe crashes...

In the case of a 16-bit binary I suspect +relay (alone) will probably be more
helpful, if it is not infeasible.

WINEDEBUG=+relay wine UC16.exe

Added relay-log from a run of UC16.exe. I haven't managed to create a relay-log
of FGP.exe as it crashes immediately.

Please note that for UC16.exe to be able to execute, the following min-address
need to be set to 0:
 echo 0 > /proc/sys/vm/mmap_min_add

Thanks. From the log:

My guess is we need to implement exception handling in interrupt 31.

WINEDEBUG=+relay wine FGP.exe

Added relay-log for FGP.exe. I'm uncertain where UC16.exe fits in, because the
FGP.exe-file did crash executing 32-bit code.
