MEH (Map Editor of Happiness) is a brand new map editor for 3rd generation pokémon games.
I haven’t found a good tutorial about MEH on the web, so I created mine.
Open MEH and go to File->Open for selecting the ROM (or just click the Open button). Maps will be loaded and listed in the left side panel, under a series of directories numbered from 0 to 32 (I’ve loaded Pokémon Ruby). These directories are map banks. Below you’ll find the list of the maps, for now double click the 0 directory, which contains cities and routes.
As you can see from the picture, each map has two numbers: the first is the map bank and the second is the map index, which identify every single map in a bank. For editing the map you simply have to select the tile from the right side panel named Tiles and then draw it on the map. Let’s remove the nord lake in Petalburg City.
You can see the actual selected tile because it’s in the red box. Now we have to edit movements. For doing this simply click the Movement tab after Tiles.
As you can see the map changes, and you can see the movements. It’s more intuitive than Advance Map, for example the blue waves stands for “Surfable”, the 2 stands for “Normal”. The edit method is the same as for the area.
Now let’s talk about events. Like in Advance Map, you have an Events tab where you can display all the events in a map.
For now, MEH can edit triggers (the green S), signs (the orange S) and warps (the purple W). For editing one of these click on them and change data.
It’s very recommended to associate MEH with a script editor (I suggest XSE).
If you go on the Wild Pokemon tab, you can change wild pokemon encounter data. Choose the environment from the combo box and change pokémon stats from the form. If you are hacking on Pokémon Fire Red you’ll be able to use time based events! Though it’s still a bit buggy, this will be a great and unique feature!
The Mime tab is actually non-sense (excuse me Shiny Quagsire, but I still didn’t understand it).
The Connections tab is interesting and very easy to use.
Open it, then you can add/change the connection simply by clicking the Add button, where a submenu will appear asking you for the direction.
A window popup ask you for the map bank you want to link, I chose Slateport City. Click the Add Connection button and close the window.
You can see the modified link in the main program 🙂 .
Remember to save changes with the appropriate button.
That’s all for now, but expect updates when the next release of MEH will appear on PokeCommunity 😉
