bnetlauncher

Launcher utility to help start battle.net games with the steam overlay.

Official page http://madalien.com/stuff/bnetlauncher/

Purpose

This application is intended to facilitate the launch of battle.net games from steam with overlay while still being auto logged in by the battle.net client.

Note: If the Battle.net client isn't running when starting the game it will be closed as soon as the game starts, otherwise it will be left running.

Howto Use

Extract the included exe to any location you want (ex: steam folder)
Add the exe to steam as a non-steam game shortcut
On the shortcut properties add one of the following parameters:

code	game
wow	World of Warcraft
d3	Diablo 3
hs	Heartstone
ow	Overwatch
sc2	Starcraft 2
hots	Heroes of the Storm
scr	Starcraft Remastered
w3	Warcraft 3: Reforged
dst2	Destiny 2 (Overlay will not work!!! See notes below)
codbo4	Call of Duty: Black Ops 4
codmw2019	Call of Duty: Modern Warfare (2019)

the result should look something like this:

"G:\Steam\bnetlauncher.exe" ow

Destiny 2

Bungie has decided to implement anti-cheat mechanisms that also cause most overlays to not work as expected.

See https://www.bungie.net/en/Help/Article/46101 for more information. If you need SteamController functionality https://alia5.github.io/GloSC/ is currently the best option.

Troubleshooting

In case of problems logging can be enabled by creating a enablelog.txt file inside %localappdata%\madalien.com\bnetlauncher\, you can open the location by pasting the path into explorer or the run dialog in windows (WinKey+R)

Aditional options

There's also the following aditional options provided by command line switches:

--timeout <seconds>, -t <seconds> changes how many seconds it tries to look for the game before giving an error (15 seconds by default).
--notask, -n starts the launcher directly instead of trying to use a scheduled task
--leaveopen, -l leaves the client open after launcher the game. If combined with --notask option it will show you as playing on steam until you close the client.

Adding more Games

From v2.00 onward bnetlauncher uses a internal gamedb.ini to control how games are launched. More games or custom configs can be manualy added by creating a gamedb.ini file in:

%localappdata%\madalien.com\bnetlauncher\gamedb.ini
the directory where the bnetlauncher executable is located.

A gamesdb.ini.sample is distributed with bnetlauncher containing a copy of the built in shortcuts.

Important: Those defaults are not changeable. bnetlauncher will always override them with it's internal gamesdb.ini file. However it is possible to create different entries with custom options.

Exemple entry:

[codbo4]
name=Call of Duty: Black Ops 4
client=battlenet
cmd=VIPR
exe=BlackOps4.exe
options=noargs,waitforexit

Explaining what each part does:

[codbo4] the id that's passed to bnetlauncher to select the game ie bnetlauncher.exe codbo4
name=Call of Duty: Black Ops 4 a friendly name for the game
client=battlenet the client the game uses, currently only battlenet is supported
cmd=VIPR command to launch the game in the client
exe=BlackOps4.exe game exe that bnetlauncher will look for after launch, can use % as a wildcard ie Diablo III%.exe to support 32 and 64 bit builds of the game.
options=noargs,waitforexit list of comma separated options, currently supported:
- noargs doesn't throw an error when retrieving blank arguments from the game
- waitforexit leave bnetlauncher open and waiting until the game existing
- nolaunch don't directly launch the game but just open the client and try to find the game for an additional 60s this can in theory be used for hacky PTR support.
- notask doesn't start the client trough a scheduled task

Known Issues

Destiny 2 will not have Steam Overlay or any associate features when using bnetlauncher. This is intended by Bungie and cannot be fixed. Steam Input users can use https://alia5.github.io/GloSC/ to work around it.
Enabling multiple instances of battle.net client in it's options might break bnetlauncher functionality.
Users of MSI Afterburner, Fraps and other overlay software might experience crashes do to incompatibility with their own overlay and steam's, to solve the issue disable the 3rd party application overlay.
The game, bnetlauncher and steam must all have the same running permissions to work properly, this means if one of them is running has Administrator/Elevated Permissions, then all of them must also be run has Administrator/Elevated Permissions.
It's not possible to automatically launch battle.net client PTR versions of games, the client provides no direct option to do this, however a workaround can be done by creating a new game entry and the nolaunch option and manualy clicking play.
Default launching the client trough a scheduled task may be incompatible with some setups, workaround is providade with notask switch/option.
Starting multiple copies of Startcraft Remastered may cause bnetlauncher to show an error since the game only allows one instance to be run at the same time.
There's no built in routine to clean up the log files if they pile up (logging is disabled by default)

Uninstalling

To remove all traces of bnetlauncher from your system:

type 'Task Scheduler' in start menu and open it, expand library and delete bnetlauncher folder to remove the tasks used to start the client
type %localappdata%\madalien.com in start menu and open the folder, delete bnetlauncher folder to remove log and gamedb.ini files
