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.
