I was just going to ask this same question
And yes, the windows state selection is grayed out in batch files, although it doesn't work for some emus anyway like Daphne, and N64 flash a loading box for a split second, and gameboy has to be in "Normal" window state to show up, so it to flashes a loading box for a split second
I think there should be a way to make a wrapper to hide that stuff I just have no idea how to do it
Anyone have any suggestions?
in the mean time I made a custom desktop theme that is Black with dark gray text so when stuff does pop up it's not as noticeable
it is very hard to read so I have another theme I use when I'm messing with the system, and it's really easy to switch back and forth
