@J.P, Galaga (great 80's arcade game btw) is where you play as a ship that stays on the same y-axis, and then you move left and right on the x-axis to shoot aliens flying in to destroy you. It's an overhead game btw.
For load, it's: LOAD "DAT:whatever you named your map when you saved it", 0. The zero is the name for the array you gave it, you may have to put the GRP4, I don't remember. Then (I think it's optional) you use BGSCREEN, but I can't remember what to put for it since it has a long syntax.
I can do that (might do it slightly wrong though)
So first, you need to make an array that stores the data for the map, we do this with DIM. It goes like this: DIM[0], 0. The first zero is for the layer of the map that you want to use. The second zero is basically the name you give the array, so since it's the layer "0", I gave it the name "0"
Then use LOAD to load the map. (cont)
*your conscience* dang it! You messed up again!!!
*little J.P demon appears on your shoulder* "it's okaaaaayyy, he won't minnnnnddd"
*little angel J.P appears on other shoulder* "but you should have the key out already!"
*the two keep arguing*
*three hours ago*
*J.P: okay just let me finish the shooting*
*Me: ok. *stares at screen**
*three hours later*
*J.P: ok, I'm making a key now*
*Me: still staring at screen. *ok!**
