Question:How do I start fresh?
  • View -> Layer 1 Mario Paths, select #lm{ow16x1}, highlight everything, press delete
  • Overworld > Change Events Passed, set all to passed, #lm{owev2}, highlight everything, delete
  • Click #lm{ow8x2}, highlight everything, delete
  • For sprites, go to #lm{owsprlist} and you can change which sprites are on the overworld.
Question:How do I make an overworld?
Answer:Click #lm{ow8x2} and then click #lm{ow8xsel} to open the 8x8 Tile Selector. Click a tile in the 8x8 Tile Selector and right-click on the overworld to paste it. Where the player walks can be changed by going to #lm{ow16x1} and selecting path tiles, then pasting them accordingly.
Question:How do I allow the player to save after a specific level is beaten?
Answer:#lm{ow16x1}, click a level and choose #lm{owlevel}, then make sure "Save prompt" has been checked. The fortress, castle, ghost house, switch palace, tile 7F, and tile 80 bring up the save prompt regardless of whether the flag is checked.
Question:The save screen shows up after a castle/ghost house is beaten. How do I remove that?
Answer:Click on Overworld -> Extra Options... and uncheck the "Bring up save prompt..." box.
Question:How do I add level 25-100 or 13C-1FF to the overworld?
Answer:You can't. The levels that can be used on the overworld are 0-24 and 101-13B. You have to save the level as one of those level numbers.
Question:How do I link Star and Pipe Overworld tiles?
Answer:First set the two tiles where you physically want them to be. Then, click the first one and go to #lm{owexstar}. Choose an exit index first (it doesn't matter which one), and then make the destination index "No setting". Go to your second tile and go back to #lm{owexstar}. Exit index is anything but the exit index you just picked for the first tile. Then, for destination, pick the index you picked as the exit for the first tile. Go back to the first tile and set the destination as the exit of the second tile.
Question:How do I change where the players start?
Answer:Click #lm{owspr} and then you can click and drag Mario and Luigi around.
Question:How do I make things happen after I beat a level?
Answer:Select #lm{owev2} and open #lm{owl2evn} to choose which tiles you want to place, and place them in the order you want them to appear. Use page up and page down to switch between events. Open #lm{owlevel} while a level is selected to see and change the event a level triggers or appears on.
Question:Can I add more types of events?
Answer:Yes. Edit the Layer 2 xxxx space to the right of the main overworld. Then, you can select it from #lm{owl2evn}.
Question:My changes to where Mario is on the overworld aren't showing up in my ROM!
Answer:Start with an "EMPTY" file.
