How to make custom tilesets?

ZC doesn't have a dedicated tileset editor, however that would be so sweet if it did

Tiles are one thing, but making the tiles usable in Zelda Classic does require you to set them up within the program

Graphics for the individual tiles can really be made in any program, as long as they follow a 16-color limitation, and can be properly grabbed into Zelda Classic with few/no recoloring issues. What program you use determines the outcome of this

However, to set up the combos, you need to do that within Zelda Classic, though it's not hard; Just time consuming

Making your own tileset isn't hard, if not easy. However, making a good tileset is the tricky part, especially if it'll be used by the masses

ok, but how exactly do i import my tiles into the program?
