More info about Fallout Et Tu: Official GitHub Repo[github.com].

• Go to Fallout installation folder
  {STEAM_DIR}\steamapps\common\Fallout
  
• Check if the file "f1_res_Config.exe" is there. If not, download the Vanilla Patch from the link above and extract the archive to your main Fallout directory. If asked, overwrite all files.

Please follow these simple steps to make the game working in high resolution.

• Run "f1_res_Config.exe" from your Fallout folder.
  
• Choose your preferred options like in the example below.
  
• Uncheck "Windowed" if you wanna run the game in Full Screen.
  In Windowed mode the game will automatically use the 640x480 resolution, but you can double the size choosing "Scaling X2". (Warning: Enable X2 scaling sometimes could cause issues with the mouse pointer or random crashes)
  
• Click on "ENABLE" to activate the HD patch.
  Text will change to: The Hi-Res Patch is Enabled.
  
• Click on "Done".

On Game's main menu, go to "Options > Screen Settings", to change screen settings on-the-fly, or some other things like the side bar art.

• Install Fallout 1 anywhere (usually "{STEAM_DIR}\steamapps\common\Fallout").
  
• Install Fallout 2 anywhere (usually "{STEAM_DIR}\steamapps\common\Fallout 2")
  
• Unpack Fallout1in2 into Fallout 2 installation folder.
  
  
  
  
• Run "Fallout2\Fallout1in2\undat.exe" and select `MASTER.DAT` file from Fallout 1 installation directory. For Linux you can use undat.sh (requires WINE).
  
• Select the "Fallout2\Fallout1in2\" folder as extraction target. Click on Extract
  
  

Run "{STEAM_DIR}\steamapps\common\Fallout2\Fallout1in2\Fallout2.exe" to start the game.


Main mod configuration can be found in "Fallout2\Fallout1in2\config\fo1_settings.ini". It is recommended to check and/or tweak settings in this file before starting a new game. Changing settings mid-game have a chance to corrupt savegames or introduce undefined behavior.

Other interesting files:

- ddraw.ini (sfall configuration)
- f2_res.ini (high resolution patch configuration)
- sfall-mods.ini, config/ directory (sfall modifications configuration)


→ Download the Latest SteamDetour[github.com] (~ 5 KiB)

Using Fallout1in2 requires to manually run the game directly from the mod directory outside of Steam. To launch the game through Steam and re-enable some useful features (Play Time, Screenshots...), you'll have to use SteamDetour as a workaround:

• Unpack SteamDetour anywhere.
  
• Open Steam -> Library -> Fallout -> (right click) Properties -> General
  
• In Launch options (advanced), use the following, {PATH_TO} is the path where Steam Detour resides, and {STEAM_DIR} is the path to your Steam installation:
  "{PATH_TO}\SteamDetour.exe" "{STEAM_DIR}\steamapps\common\Fallout2\Fallout1in2\Fallout2.exe" %command%
• Run the game via Steam
