 To migrate tilesets that have been previously created for pokefirered you can use [this script](/migration_scripts/frlg_metatile_behavior_converter.py).<br>
 Instructions are in the script.
 
+## Creating a new tileset
+If you create a new tileset after the changes made above Porymap will define that tileset's metatle attributes as u32 like this
+
+```diff
++const u16 gMetatiles_General_Platinum[] = INCBIN_U16("data/tilesets/primary/general_platinum/metatiles.bin");
++const u32 gMetatileAttributes_General_Platinum[] = INCBIN_U32("data/tilesets/primary/general_platinum/metatile_attributes.bin");
+```
+
+Which would be fine if it was pokefirered but in pokeemerald they should be u16
+
+Make the following changes to make them u16
+```diff
+const u16 gMetatiles_General_Platinum[] = INCBIN_U16("data/tilesets/primary/general_platinum/metatiles.bin");
+-const u32 gMetatileAttributes_General_Platinum[] = INCBIN_U32("data/tilesets/primary/general_platinum/metatile_attributes.bin");

 ## Fix CI if you are building FRLG by default
 If you make these I would also reccomend fixing your CI too to match these changes
