Sure, it took some time for me to redo al lsprites...but instead I could have changed one argument in a function I was using to load the ressources and it would have automatically removed the background color.
But this would have prevented us from using partially transparent colors...and I rly wanted those.
Well if you wanted to do it the lazy way you could have just done an if statement and had it remove the background if say the id was < #. But then again, I'm not sure if that would even work based on how you list them but whatever. lol
