- Since re3 is a DLL that works with original GTA III for now, you need Simple DLL Loader. You can get it [here](https://github.com/aap/simpledllloader).
|
||||
- Build re3 or download it from one of the above links (Debug or Release).
|
||||
- Make sure you included the re3 in `plugins.cfg` or `dlls.cfg`.
|
||||
- re3 starts the script `main_freeroam.scm` that comes along with it by default, so you should copy it to from `gamefiles/` to your game's `data/` directory.
|
||||
|
||||
 **Notice**
|
||||
|
||||
If you want to load original script/story, press and hold G while game is loading.
|
||||
This includes both starting new game and loading save game.
|
||||
|
||||
 **Notice if you will build it**
