3. Extract your game to `orig/[GAMEID]`. In Dolphin, use "Extract Entire Disc" for GameCube games, or use "Data Partition" -> "Extract Entire Partition" for Wii games.
4. Rename `config/GAMEID` to the game's ID and modify `config/[GAMEID]/config.yml` appropriately, using [`config.example.yml`](/config/GAMEID/config.example.yml) as a reference. If the game doesn't use RELs, the `modules` list in `config.yml` can be removed.
6. Modify the paths in `config/[GAMEID]/build.sha1` to point to the `build` directory instead of `orig`. The DOL will be built at `build/[GAMEID]/main.dol`, and modules will be built at `build/[GAMEID]/[module_name]/[module_name].rel`.
If all goes well, the initial `symbols.txt` and `splits.txt` should be automatically generated. Though it's likely it won't build yet. See [Post-analysis](#post-analysis) for next steps.
## Using a `.map`
If the game has `.map` files matching the DOL (and RELs, if applicable), they can be used to fill out `symbols.txt` and `splits.txt` automatically during the initial analysis.
Add the `map` key to `config.yml`, pointing to the `.map` file from the game disc. (For example, `orig/[GAMEID]/files/main.map`.) For RELs, add a `map` key to each module in `config.yml`.
If the game uses [common BSS](common_bss.md), be sure to set `common_start` as well. (See [`config.example.yml`](/config/GAMEID/config.example.yml).) Otherwise, the final link order may fail to be determined.
Once the initial analysis is completed, `symbols.txt` and `splits.txt` will be generated from the map information. **Remove** the `map` fields from `config.yml` to avoid conflicts.
## Post-analysis
After the initial analysis, `symbols.txt` and `splits.txt` will be generated. These files can be modified to adjust symbols and split points.
If the game uses C++ exceptions, it's required to set up a split for the `__init_cpp_exceptions.cpp` file. This differs between linker versions.
Often indicated by the following error:
```
# runtime sources 'global_destructor_chain.c' and
# '__init_cpp_exceptions.cpp' both need to be updated to latest version.
