Batman Arkham Knight Riddler Trophies Save File Fix

If your Riddler trophy progress is bugged, missing, or corrupted in Batman: Arkham Knight

, you can resolve it by using the game's built-in backup system or manually restoring save files on PC. Built-in "Previous Save" Feature

Batman: Arkham Knight automatically maintains backup checkpoints that can be accessed without digging into system folders. Launch the game and stay at the Save Slot selection screen. Highlight the slot that has the bugged progress.

Controller: Hold LB + RB (Xbox) or L1 + R1 (PlayStation) for about 10 seconds.

PC/Keyboard: If the controller shortcut doesn't trigger, some users have had success using the Previous Save feature to revert to an earlier state.

A list of backup saves with timestamps will appear; select one from before the glitch occurred. Manual PC Save Restoration (Steam) batman arkham knight riddler trophies save file fix

If the in-game menu doesn't work, you can manually swap files in your Steam directory.

Remote Save Location: Navigate to your active saves at Steam\userdata\[Your User ID]\208650\remote. The Fix:

Find a backup file with a timestamp (e.g., BAK1Save0x0_2023-01-01_12-00-00.sgd). Copy it into the remote folder.

Detailed Functionality Breakdown

4.1 Primary Fix (All Platforms) – Restore from Backup

If you have a manual or cloud backup from before the corruption:

  • PS4/PS5: Settings > Application Saved Data Management > Download from cloud or USB.
  • Xbox: Manage game > Saved data > Delete local save (force resync from cloud).
  • PC (Steam):
    1. Disable cloud sync temporarily.
    2. Navigate to \Steam\userdata\<userID>\208650\remote\
    3. Replace BmGameSave_*.sav with backup.
    4. Re-enable cloud sync.

1. The "Ghost Trophy" Scanner (Orphan Detection)

  • How it works: When the tool loads the save file, it compares the player's current progress against a canonical map of all 243 Riddler Trophies.
  • The Fix: It identifies trophies that are marked as "Not Collected" in the save file but are physically impossible to collect in the game world (because they have already vanished/despawned due to the player having visited that specific grid coordinate previously).
  • Result: The tool flags these as "Ghost Trophies" and updates the save file to mark them as collected, restoring the correct total count without touching trophies the player legitimately hasn't found yet.

The Nuclear Option: Save File Editors

For PC players, the Batman: Arkham Knight Save Editor (created by modder "Gibbed" and updated by the community) is the holy grail.

  • How it works: You load your save, click the "Riddler" tab, and check a box that says "All Trophies Collected."
  • Result: The game instantly registers that you have beaten Riddler. You can go straight to the final fight without redoing any puzzles.
  • Warning: This will not give you the achievement for "Brutality 101" or "Point of Impact," but it will unlock the final Riddler boss fight and the 100% ending.

Method 1: The "Progression" Bypass (The Easiest)

If you are stuck at 242/243 and the last trophy is glitched: Disable cloud sync temporarily

  1. Navigate to your save folder: \Documents\WB Games\Batman Arkham Knight\SaveData
  2. Backup your save file. (Copy GameSave_x.sav to your desktop).
  3. Download a 100% completion save file from a reputable modding site (Nexus Mods or Speedrun.com).
  4. Replace your file with the 100% save.
  5. Note: This will change your character skins and story progress. Only use this if you just want the "Knightfall" ending.

3. Diagnosis

To confirm the issue:

  1. Check in-game Riddler tab for inconsistent counts (e.g., 242/243 in Founders’ Island but no trophy visible on map).
  2. Compare save file timestamps between local and cloud copies.
  3. On PC, open BmGameSave_0.sav (or ..._1.sav for NG+) in a hex editor – partial trophy data may appear as repeated or null flag sections.

The Console Fix (PS4/PS5 & Xbox)

Unfortunately, Sony and Microsoft do not allow users to manually edit save files without jailbreaking the console (which we do not recommend). However, there is a brute-force method that works sometimes:

The "Collector’s Instinct" Workaround:

  1. Delete your local save file (do not delete the cloud backup).
  2. Uninstall the game.
  3. Reinstall the game without updating to the latest patch (play using version 1.00 from the disc).
  4. Load your cloud save. Older game versions sometimes ignore the glitch flag.
  5. Collect one single Riddler informant. Interrogate him.
  6. This often resets the map logic. If the trophy appears, grab it, save, then re-update the game.

If this fails on console, you have two options: Start a New Game Plus (progress carries over) or admit defeat. Many players have simply watched the "Knightfall Protocol" on YouTube rather than re-collect 200+ green trophies.

4.5 Checksum Recalculation

The game uses a simple 32-bit XOR checksum over the entire file except the last 4 bytes.

  • Calculate XOR from byte 0 to (filesize – 5).
  • Write result to last 4 bytes (little-endian).

Pseudocode:

checksum = 0
for i = 0 to filesize-5:
    checksum ^= buffer[i]
write checksum at filesize-4
