1. Add the map files to `Rabi-Ribi\custom\<your map name>`. (each custom map should be in its own folder)
2. After starting Rabi-Ribi, press F5 or F6 to open up the [custom maps menu](https://user-images.githubusercontent.com/27341392/30108930-ee520480-9336-11e7-9a82-bf40ca1ae89e.png). Select the custom map and start a new game.
Rabi-Ribi (1.8e/1.85 onwards) includes the ability to modify cutscenes and character dialogue for custom maps. By default, the game makes use of the files in `Rabi-Ribi\localize` for its cutscenes. If you create the files `story_emot.rbrb` and `story_text.rbrb` and place them in your custom map folder (`Rabi-Ribi\custom\<your map name>\`) together with your map, these ifles will be used for dialogue/cutscenes instead.
More information on the contents of these files can be found in the [Detailed Documentation](https://github.com/wcko87/rabiribi-map-editing/tree/master/docs/cutscenes).
Rabi-Ribi (1.8e/1.85 onwards) includes the ability to replace the current tileset with a custom tileset. If `tile1_a.png` is placed in the `Rabi-Ribi\custom\<your map name>\` folder, the game will use that instead of the default tileset.
Rabi-Ribi (1.8e/1.85 onwards) contains a Debug mode, which displays all event triggers in-game. To turn this on, add `-debugshowevents` to the launch options.
