well, the only way I know how to do a splitscreen is to make a ton of different active objects. You have to make all the obstacle backdrops be active objects, make 2 active objects per object(1 for 1st player screen and one for 2nd player). Then you have to move the X,Y coordinates of everything on a screen instead of using regular scrolling.
The only other way to do this is to use a splitscreen extension that I've never heard of.
make two applications, in one put the two players with whatever movement you want, but make the screen scroll just follow player one. in the other application again put the two players, this time with a static movement, and make the scroll center now on player 2.
the idea is to always make an ini save the positions of the objects of window one and make window 2 load them
ugh, using inis is terrible especially if it's constant
