The test results you have selected are very old and may not represent the current state of Wine.
Selected Test Results (selected in 'Test Results' table below)
Almost everything. Gameplay, all sounds and music, videos and multiplayer (needs DLL overrides for DirectPlay) via TCP/IP using Hamachi. Problems with multilplayer.
What does not
Multiplayer is unstable, it disconnects randomly (receiving some Wine error dialogs then disconnecting from game), sometimes causes infinite hangs (then need to kill the game), I don't know the reason. I played via TCP/IP using Hamachi (version 188.8.131.52, beta quality).
What was not tested
Admin note: rating changed to conform to the rating definitions.
Multiplayer To get multiplayer working, place dpnsvr.exe and the DLLs in this archive
in Wine's windows/system32 directory. Then, start winecfg and add dll
overrides (native, builtin) for the following DLLs: dplayx, dpnet,
dpnhpast and dpwsockx. Finally, update your registry by running 'wineprefixcreate'.

To Solve Multiplayer possible crashes where connection drops

Not sure if this helps anyone with the frequent connection drops when playing a multiplayer game, But seemed to solved my problem.
Game would play for around 3 to 5 turns then crash out do to a connection being dropped.
my work around.
Seems to work when you run regsvr32 dpnet.dll before starting the heroes 4 game in wine.
This is tested with Heroes of might and magic 4 plain version 2,2. Also using the instructions above to get Multiplayer to work.

A workaround for poor performance and a way to get better graphics:
1. If your screen is big enough, set a virtual desktop size in winecfg to 1600x1280. If not (or if you want a custom number), any size bigger or equal to 1280x1024 (it has to have a ratio of 1:1.25 or similar) will do.
2. Launch Heroes of Might and Magic IV, go to Game Settings and set these parameters:
Screen Resolution: 1280x1024
Full Screen: V
3. Here you go, it gives you additional information and makes numbers and characters bigger while maintaining good performance.
4. Once you're done, uncheck Full Screen and exit the application.
If you forgot to uncheck Full Screen before exiting, you will have to enter "wine regedit.exe" in your console, navigate to "HKEY_CURRENT_USER\Software\New World Computing\Heroes of Might and Magic IV" and change the key "full_screen" to "0" (which means disabled). Otherwise it won't start.
