Mapedit – “Gray’s Mapper” – Live

How to load a map: Click inside the DOS window, then press F3 to open the file manager. On a MacBook, you may need to hold Fn while pressing the function-key row. Navigate to the MAPS folder and open a map file. Select the .. row to navigate back up out of the folder you are in. Use the arrow keys to move the pink asterisk — the map will be revealed as you move.
Help: Press F1 while editing a map to view the built-in key guide. The full manual and release notes are separate text files and are best opened from the webpage. <
