Assassin's Creed Odyssey

Forger v2 is intended to simplify patch installation for games that use Forge files (AC Odyssey, AC Origins)


Installing version 2

  1. If you were a Forger v1 user, stop and follow the migration instructions below
  2. Extract the EXE and DLL files to a convenient folder (it doesn't matter where)
  3. Launch Forger.exe and click the Locate button at the end of the Game Folder line
  4. Browse to your game installation folder and open its main EXE file (e.g.  ACOdyssey.exe in C:\Program Files (x86)\Steam\steamapps\common\Assassin's Creed Odyssey)
  5. Forger will create a ForgerPatches folder inside of your game install folder that will hold your patches.

To install/update/remove patches:

  1. Extract/copy patch collection files (*.forger2)  from Nexus into the ForgerPatches folder in your game installation path.  There is no need to remove older versions of these files.
  2. Open Forger or click the Rescan button
  3. New patches will be highlighted in yellow, and updates to existing patches will display in green.
  4. Click the check next to each patch you want to install.  The first installations will take some time as a new backup (*.original) file is created


Misc/FAQ

DO NOT delete the *.original files.  These were optional in v1 but are required for v2.  You will need to allow for extra disk space to hold them.


Migrating from version 1 (one time only!)

If you were a v1 Forger user (game version 1.2) and this is your FIRST time installing v2, there are additional instructions for you to follow.  This is a result of the game 1.3.0 update.

Locate the following files in your game folder:

  • DataPC_patch_01.forge
  • DataPC_patch_01.forge.original
  • DataPC_15_dlc_patch_01.forge
  • DataPC_15_dlc_patch_01.forge.original

For each pair of files, compare the file sizes between the forge and forge.original copies.  If they are different, delete or rename the .original copy.

If Forger v2 was open while you were making changes, close and reopen it before trying to install any patches.

Proceed with the installation instructions.  Note that Forger v1 files (*.forger) are not compatible with version 2.


Restoring the game

If the game fails to start and uninstalling patches doesn't resolve the problem, you can uninstall manually.  For each *.forge.original file in your game folder and its dlc_* subfolders:

1.  Rename, move, or delete (to the recycle bin where you can retrieve it) the corresponding *.forge file with the same name
2.  Rename the *.forge.original file to *.forge
3.  Try starting the game.  If it launches, rename the forger2.xml file in the ForgerPatches before starting Forger again.
4.  If the game does not launch, use the verify/repair function for your game installation:

Steam: https://support.steampowered.com/kb_article.php?ref=2037-QEUH-3335
Uplay:  https://support.ubi.com/en-US/Faqs/000025650/Verifying-Games-In-Uplay-UPC

5.  When it completes, verify that all *.original files are out of the game folder and that the forger2.xml has been renamed.

    Hi, I followed all the instructions that are listed above. But whenever I go into the game, the mod is not working. Did I miss anything?
    I installed forger v2 then downloaded the mod files and pasted on ForgerPatches then clicked the checkboxes... Please help.

      Passed unanimously by the House of Representatives along with scores of other amendments, it said that the expansion and aggression of the People's Republic of China in and around disputed territories, such as the Line of Actual Control, the South China Sea, the Senkaku Islands, is of significant concern.

    Hi, I downloaded forger and added to forge files into the folder, they show up and I can tick them, but the "install updates" button will always be grayed out so i cant click it. Any idea why this would happen?

    Mod Does Not work. I have a valid purchase of the copy both on steam and uplay (Wont show because its not really your business). Iv followed your steps and even the manual and it makes no since at all on how to activate the mod in the game. TBH This was a good try however a shitty job in trying to help others by asking people to proof its a legal copy when legal copy or not isnt the issue its the mod and forger 2.8 (current version of that mod now. I was able to open the game no error code while having the nude mods Open and running on the forger and clicked the check boxes but nothing in the game at all was changed. I checked customization's and the npc's as well as double checked to see if it was even on. There is no way to tell. Maybe this worked in 2019 but ACO is pretty strict about the Nude mods and are always making it pretty hard to keep unlike other games like ESO, SWTOR. Unless there is a way to actually solve this problem instead of telling players to "Buy the Legal game" This mod is broken. Its 6/6/2020 and the last post on this was last month with no reply from the maker of this mod. Find another site or mod, or Do what i like to do and keep the game original.

      Oh, where to start... I'm not sure how I missed this gem of a comment, but Nexus' notification system isn't the greatest.

      I have no idea what your original complaint was, but people are still posting screenshots to my mods and commenting that they're working well. If I replied to you personally telling you to buy the game, it's because you posted an error that gave you away. If you had the latest game, you wouldn't be getting errors. Simple enough.

      Maybe this worked in 2019 but ACO is pretty strict about the Nude mods and are always making it pretty hard to keep...

      You're basing this on what, exactly? I have never been contacted by anyone claiming to represent Ubisoft, nor have I seen any anti-modding measures in ACO.

      My favorite line though is where you post, to a modding site, that mods are bad and everyone should just play the vanilla game. I'm sure that's convinced a whole lot of people! ;)

    Seems pretty straightforward. I get no errors, but I also don't get the install update button to un-grey itself out. Can't install the mods I've ticked the boxes for. So not surprisingly, mods don't show up in game. Forger made the Forger Patches folder. My mods are upacked into it, just three mods. They show up in the forger window and when I tick boxes they accurately bring up the choices for me to tick.

    But that install button stays grey so can't install them.

      Mods are applied the instant you click on the checkbox. If you're not seeing the expected effects in game, review the documentation for the mod. You've probably missed a step.

    Once I check the boxes for the patches i want to install, do I just 'X' out of the small window? Or is there anything else i need to do?

    My problem was that I overwrote d3d11.dll with dxgi.dll and deleted the dxgi.dll, this stopped it from loading with UPlay overlay, solved now by replacing the d3d11.dll with dxgi.dll and keeping the dxgi.dll as well. Hope it helps anyone that had the same problem with CTD on splash screen after some loading. Works with Uplay too.
     
    I did have to reinstall the game to get it running but possibly it wasn't necessary as it might have just need that dxgi.dll in place after simple install verify of game files in either stam or uplay and reapplying all the patches.
     
    Step by step update guide for me was.
     
    !! Step 1 and 2 are possibly optional !!
    1. Search all game folders for .original files.
    2. Replace the game files with originals.
    ------------------------------------------------------------
    3. Either Steam or Uplay installation files verification.
    4. Install Resorep.
    5. Install Forger.
    6. Copy dxgi.dll over d3d11.dll in game folder while keeping the dxgi.dll in place.
    !! OPTIONAL if anyone uses Reshade and say... ACE !!
    7. Install Reshade 3.4.1
    8. Copy over ACE files.
    9. Fix paths in reshade.ini.
    10. Run game.
     
    Fingers crossed it, should work fine at least it does now for me.
    Thou I did reinstall the whole game first so keep in mind it might not have been just the dxgi.dll thingy.

      I think I might be having the same issue. where do I get the dxgi.dll and d3d11.dll? they aren't in my game folder. also what do you mean by copy over? do you mean overwrite?

      any help would be appreciated.
