Guys this problem falls perfectly in a suggestion that I've wanted to do for quite some time now, but never did, so here it goes...
Before using LB to launch my games, i've used to have 1 script for each PC game and each emulator, what this script does is: 1- Show a splash screen with the game's fanart 2- Launch the game. 3- Wait for the game specific window to show up 4- If window exists, i could set things like borderless windo to games that don't have it, and other stuff... 5- When it's done, close the splash screen and show the game window.
This way all the garbage that some games and specially emulators from before launching the actual game gets hidden and we never get to see it.
It Would be awesome if you could add something like that to LB, i guess it should be very easy, cuz even i could manage to do it with AutoHotkey...
This way we would't have to guess how much time each game takes to load exactly to only then set that "timer" to each game.
I'll attach a copy of the script i've used before LB, you could take a look and see if it's possible to port it to LB, this is the only thing that my old "setup" does better than LB.
