Edit KINGDOM HEARTS III.exe with a hex editor[7][8]
  1. Go to <path-to-game>\KINGDOM HEARTS III\Binaries\Win64 and open KINGDOM HEARTS III.exe in a hex editor, such as HxD.
Pillarbox fix
  1. Search for AC 8B E3 3F 39 and replace AC 8B E3 3F with the hex value for the desired screen aspect ratio found from the WSGF's Common Hex Values page to offset the game's custom pillarboxing functionality.
  2. Search for C7 80 28 04 00 00 3B 8E E3 3F, C7 83 08 04 00 00 3B 8E E3 3F, and C7 83 28 04 00 00 3B 8E E3 3F, and replace the 3B 8E E3 3F portions with the hex value for the desired screen aspect ratio found from the WSGF's Common Hex Values page to offset Engine specific functions that are used for pillarboxing during gameplay and cutscenes.
UI and FMV stretching fix
  1. Search for F3 0F 5E C8 F3 0F 10 35 EE 58 13 04 and replace with F3 0F 5E C8 F3 0F 10 35 F2 58 13 04 to fix the UI and cutscene stretching that occurs from modifying the value in Step 2.
Field of view fix
  1. Search for 35 FA 0E 3C BC 74 and replace with 35 FA 38 3C BC 74 for a 21:9 aspect ratio, EF F4 38 3C BC 74 for a 32:9 aspect ratio, or EF D4 83 3C BC 74 for a 48:9 (3x 16:9) aspect ratio.

    Game does not exit when an internet connection is lost, but the player cannot progress past certain points in the story without an internet connection, and the game will throw an error message asking to go online when such points are reached. If "retry" is pressed, gameplay continues, but the player won't be able to progress further in the story, and the room that progresses the story will be inaccessible until an internet connection is re-established.
