I wrote a simple AutoHotKey script, it does 5 things
1) Start BigBox
2) Start the animation you want (infinite loop mode)
3) Wait the duration you want (it should be the duration of your startup video)
4) Stop the animation
5) Send the "Game Stop" command to ledblinky in order to display the Launchbox controls.
#Persistent
SendMode Input ; Recommended for new scripts due to its superior speed and reliability.
SetWorkingDir "C:\HyperSpin\Utilities\LEDBlinky" ; Ensures a consistent starting directory.
Run, C:\Roms\LaunchBox\BigBox.exe ; Starts BigBox, you should replace it with your own BigBox path
Run, C:\HyperSpin\Utilities\LEDBlinky\LEDBlinky.exe Pattern73.lwax ; Patter73.lwax represent the animation you want to play, the file must be in your ledblinky lwax directory
SetTimer, mytimer , 20000 ; Set the timer to stop the animation, the value is in ms
return
mytimer:
SetTimer, mytimer , Delete ; Delete the timer
Run, C:\HyperSpin\Utilities\LEDBlinky\LEDBlinky.exe 11 ; Stop the animation
Run, C:\HyperSpin\Utilities\LEDBlinky\LEDBlinky.exe 4 ; Send the game stop signal to display the launchbox controls
ExitApp
return
