So I made a scratch NG preloader that you guys can use and yes I fully coded it for you
and some code you might alter depending if your backdrops have different names you just have to change those names if they do have different names and I made my own variables that get the data etc.(don't alter any of the code unless your backdrops have different names just change bg 1 to whatever and I might make another one and you have to make this your first bg or it won't work) and here is the file just open up the zip and take out the sb3 etc enjoy bye
