Configuration

All configurations are done by zlauncher.ini config file. ZLauncher can use another config file if specified with -config command line parameter.

This is an example config file:

[cemu]
path=D:\Programs\Cemu                                          ; Path to Cemu
fullscreen=true                                                ; Fullscreen
cores=0,2,4,6                                                  ; Comma/space delimited list of allowed cores
cmdline=                                                       ; Additional Cemu command line parameters

[game]
path=D:\Games\WiiU\The Legend of Zelda - Breath of the Wild    ; Path to the game
elevate=true                                                   ; Run game with admin priveleges

[speedhack]
path=.\speedhack.exe                                           ; Path to speedhack trainer
enabled=false                                                  ; Is speedhack enabled

[video]
enabled=true                                                   ; Video playback hack enabled

[steam]
enabled=true                                                   ; Is Steam support enabled
elevate=true                                                   ; Run Steam with admin priveleges
gameid=12927812811798609920                                    ; Game id in Steam library

Video playback

ZLauncher supports BotW cutscenes playback using external mpv player. ZLauncher reads Cemu log file and starts playing when game tries to access video file. To enable video playback hack:

• Enable logging in Cemu (Debug > Logging > Enable logging and Debug > Logging > File access)
• Set the [video].enabled parameter to true

Steam (overlay and controller)

You can launch game through Steam to get Steam overlay and Steam controller working:

• Add ZLauncher into your Steam library as a Non-Steam game
• Create desktop shortcut for this game
• Find new shortcut on desktop and open its properties
• Copy id number from URL attribute. It will be something like steam://rungameid/12927812811798609920
• Paste id to the gameid parameter of the [steam] section
• Delete shortcut if you want
• Set the [steam].enabled parameter to true
• Set the [steam].elevate and [game].elevate parameters to true if you want to run game as admin
