I am currently finished up to level 2 for Lode Runner and to level 1 for Championship Lode Runner. For future reference, on the map page there is a yellow square where I have no longer written any hints and a red square where I have no longer written any maps.
These are all 10x11 gifs, enlarged by a factor of 2 each way so they show up the actual Apple emulator size. I've taken the graphics off a black&white emulator so these should be accurate.
The colors are as follows: blue for cement/bricks/outside of false bricks. Chests white and red, robots white and red.
Click on the picture for the bmpmake source code.
1=brick(can dig through it)
2=cement(can't dig through it)
4=rope ladder(can move across it)
5=false brick(can't dig through it, but you'll fall through it unless you are on a ladder/rope. You can also go down through it.)
6=ladder that appears after you've cleared the level.
