~NO SAVING YET!!!
Mp22 Early Zelda engine with map editing capabilities.
So I figured out how to go making my own map editor.
This means I've figured out (simultaneously) how to add collision to large scrolling maps.
It's not that hard so I'll blog about it later.
For now here's something to try out. The editor works use A+D-pad to select tiles.
Use touch screen to place them.
Up down left or right will scroll you a whole screen over up or down (Any direction)
You may modify this to your own delight if you please.
I take no responsibility for the hours you may spend trying to make a map that you can not save.
