# How to use FireRed/LeafGreen
|
|
|
|
## How to compile
|
|
```make firered -j<output of nproc>```<br>
|
|
or<br>
|
|
```make leafgreen -j<output of nproc>```
|
|
|
|
Note: If you switch between building emerald and FRLG, `make clean` is required at the moment.
|
|
|
|
## Porymap adjustments
|
|
For Porymap to work with FRLG maps you need to adjust a few settings (`Options > Project Settings`):
|
|
- in the `General` tab change the base game version to `pokefirered`
|
|
|
|
|
|
|
|
- in the `Identifiers` tab change the following attributes:
|
|
- define_tiles_primary: `NUM_TILES_IN_PRIMARY_FRLG`
|
|
- define_metatiles_primary: `NUM_METATILES_IN_PRIMARY_FRLG`
|
|
- define_pals_primary: `NUM_PALS_IN_PRIMARY_FRLG`
|
|
- define_mask_behavior: `METATILE_ATTR_BEHAVIOR_MASK_FRLG`
|
|
- define_mask_layer: `METATILE_ATTR_LAYER_MASK_FRLG`
|
|
|
|
|
|
|
|
## How to add maps
|
|
For maps to be included in the firered build process they need to have a custom attribute `region` with the value `REGION_KANTO`. Not defining this attribute defaults to `REGION_HOENN`. The attribute can either be added in porymap or manually in the `map.json` file.
|
|
|
|
**Examples:**
|
|
|
|
map.json:
|
|
```
|
|
{
|
|
"id": "MAP_PALLET_TOWN",
|
|
"name": "PalletTown_Frlg",
|
|
"layout": "LAYOUT_PALLET_TOWN",
|
|
"music": "MUS_RG_PALLET",
|
|
"region": "REGION_KANTO",
|
|
...
|
|
```
|
|

## Migrating FRLG tilesets
|
|
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.
