# ⚾ Baller
Modding tools for Backyard Sports, with support for:
- Backyard Baseball 1997/2001
- Backyard Soccer
- Backyard Football
- Backyard Basketball
This project also hosts a [decompilation of Backyard Baseball 2001](https://github.com/whatisaphone/baller/tree/browse).
## Tutorial
Let's extract Backyard Baseball 2001's scripts, modify one of them, and rebuild the game.
Before you start of course, [download the latest release](https://github.com/whatisaphone/baller/releases). Open a terminal and run `baller --help` to make sure it works.
1. Pick some directories to keep your project in. This tutorial uses:
- `~/bb2001src` as the project directory, for the extracted source files.
- `~/bb2001game` as the output directory, for the compiled game you can run.
2. Copy your original game files to `~/bb2001game`. Make sure to include all the original data files: `baseball 2001.he0`, `baseball 2001.(a)`, etc.
Before you start, you could try running the game from this directory with ScummVM to make sure your untouched files are working.
3. Extract the assets to your project directory:
```sh
baller extract ~/bb2001game/baseball\ 2001.he0 ~/bb2001src
```
This will write project.txt, some supporting files, and one directory per room.
4. Modify a script. The file `baseball/RMDA/LSC2_0013.s` contains the hover text for the main lobby. Change line 105 from "Meet the players" to "Meet the modders".
5. Build the assets. This will **overwrite** `baseball 2001.he0` and other files in the output directory.
```sh
baller build ~/bb2001src/project.txt ~/bb2001game/baseball\ 2001.he0
```
Now when you run the game, it will use your changed text:
### Talkies
Modifying talkies is similar. Briefly:
```sh
baller talkie extract ~/bb2001game/baseball\ 2001.he2 ~/bb2001talkies
baller talkie build ~/bb2001talkies/talkies.txt ~/bb2001game/baseball\ 2001.he2
```
