--- Comment #297 from Anastasius Focht <focht at gmx.net> ---
Hello Bjoern,

--- quote ---
Since when is this needed for wow?
This about the  KUSER_SHARED_DATA feature needed by games like swtor.
Wow needs the exception fixes  that this patch depends on it's current ( older
patches didn't depend on this).

I downloaded multiple Blizzard games: the 64-bit and 32-bit variants if
available. For testing I used a 64-bit WINEPREFIX with full install and a
helper 32-bit WINEPREFIX with has symlinks to allow testing both versions
(32-bit and 64-bit) if present.

I should have been more explicit though, the are some differences when 32-bit
or 64-bit version is used. Some of Blizzard's major titles/games seem to share
parts of the anti-cheat/debugging code.

===
Overwatch (64-bit): 
===

--- snip ---
./drive_c/Program Files (x86)/Overwatch/Overwatch Launcher.exe: PE32 executable
(GUI) Intel 80386, for MS Windows
./drive_c/Program Files (x86)/Overwatch/Overwatch.exe: PE32+ executable (GUI)
x86-64, for MS Windows
--- snip ---

NOTE: requires additional patches

===
StarCraft II (32-bit and 64-bit):
===

--- snip ---
./drive_c/Program Files (x86)/StarCraft II/Support64/SC2Switcher_x64.exe: PE32+
executable (GUI) x86-64, for MS Windows
./drive_c/Program Files (x86)/StarCraft II/StarCraft II.exe: PE32 executable
(GUI) Intel 80386, for MS Windows
./drive_c/Program Files (x86)/StarCraft II/Versions/Base62848/SC2_x64.exe:

./drive_c/Program Files (x86)/StarCraft II/Versions/Base62848/SC2.exe: PE32
executable (GUI) Intel 80386, for MS Windows
./drive_c/Program Files (x86)/StarCraft II/Support/SC2Switcher.exe: PE32
executable (GUI) Intel 80386, for MS Windows
--- snip ---

--- snip ---
$ wine ./StarCraft\ II.exe OnlineService.SSO=true -launch -uid
--- snip ---

--- snip ---
$ wine64 ./Support64/SC2Switcher_x64.exe
--- snip ---

Correction: SC II seems to work without KUSER_SHARED_DATA patch (runs at least
until login screen) -> sorry about that.

===
Diablo III (32-bit and 64-bit):
===

--- snip ---
./drive_c/Program Files (x86)/Diablo III/x64/Diablo III64.exe: PE32+ executable
(GUI) x86-64, for MS Windows
./drive_c/Program Files (x86)/Diablo III/Diablo III Launcher.exe: PE32
executable (GUI) Intel 80386, for MS Windows
./drive_c/Program Files (x86)/Diablo III/Diablo III.exe: PE32 executable (GUI)
Intel 80386, for MS Windows
--- snip ---

NOTE: requires additional patches

32-bit version started working when KUSER_SHARED_DATA patch was applied on top.

--- snip ---
$ wine64 ./Wow-64.exe
...

--- snip ---

I cherry-picked single patches from Wine-Staging without dependencies to figure
out the minimum set and drop unneeded dependencies. The 64-bit exception code
patch alone which is listed as dependency didn't resolve the issue for the
64-bit versions.

I'm correcting the summary to explicitly refer to 32-bit Diablo III, 32-bit WoW
and Overwatch until further results.

Regards
