Jumping on the bandwagon here! This is my map maker/editor that i have used to make rooms for Serenity. It uses my patented* duel sprite technique to create the maps, and so has a vast number off possible tiles.
[arrow keys]: moves your cursor
[2nd]: Lets you input a string of 2 characters, displaying them where your cursor is
[Alpha]: brings up a screen of many special chars and lets you select 2 for even more possibilities
[Clear]: Clears the current tile
[Mode]: Repeat the most recent tile
[Enter]: save to Str1 and Str2
I'll get a screenshot up as soon as i get calcapture back up and running
*Not really patented
