How to fix Kingdom Hearts 3 Ultrawide Issues on PC

Kingdom Hearts 3, along with a bunch of other titles in the series are finally out on PC. Square Enix has released these on the Epic Games Store, and most of these ports are very good. Performance is fantastic all around, and players have the option to choose higher framerates as well. This doesn’t mean the port is perfect, however, and this seems to be a common trend for a lot of PC releases. The ultrawide support is lacking, and we doubt it will be patched in. If you want to fix the Kingdom Hearts 3 Ultrawide Issues, here is how you can do that.

The PC version is exclusive to the Epic Games Store, and we expect these games to come out on Steam, and other clients after a year. Hopefully, even more console exclusives can make their way to PC as well. Sony recently announced that they plan to bring multiple games to PC, including Days Gone, which comes out on Steam, and Epic Games Store this Spring.

Fixing Kingdom Hearts 3 Ultrawide Issues

As we previously mentioned, even though the port is pretty good, ultrawide support is completely lacking. If you have read our previous guides for ultrawide fixes like this before, this guide isn’t that different from that, though it does go into more detail.

Download and install HxD

• First, you need to download and install the HexEditor

Launch and use HxD

• Launch HxD, which you previously installed
• Now, head over to where the game is installed (Kingdom Hearts III), and navigate to the following folders

Binaries\Win64

• Here, drag KINGDOM HEARTS III.exe into HxD, and a bunch of values will show up

Pillarboxing

• Press CTRL+R, and then select Hex-Values
• After this click on Search Direction “All”
• In the search Window, you want to enter AC 8B E3 3F 39 and replace it with the value corresponding to your aspect ratio, from below (thank you WSGF for providing these)

• Since we are doing this guide for 32:9, we will use 39 8E 63 40

Pillarbox Continued

Moving on, you want to do the same with the following three values, with a key difference. In the values mentioned below, you only want to replace the 3B 8E E3 3F part.

• 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

To do this, follow the steps below

• Simply press Ctrl + F together to bring up the Search Window
• Here, click on Hex-Values, and then enter one of the values from above, in this case, we have entered C7 80 28 04 00 00 3B 8E E3 3F
• Set Search Direction to All, and then click Search All

• This will highlight the searched value in the main window

• Now, select the 3B 8E E3 3F part, and replace it with the appropriate value from the table above
• Since we are doing this guide for 32:9, we will replace it with 39 8E 63 40, by simply copy-pasting

• After you do that, it will look like this

Repeat this for C7 83 08 04 00 00 3B 8E E3 3F and C7 83 28 04 00 00 3B 8E E3 3F

UI

Now, we will be fixing the UI. This is simple, and you can do it by following the steps below.

• Search for F3 0F 5E C8 F3 0F 10 35 EE 58 13 04 and replace it with F3 0F 5E C8 F3 0F 10 35 F2 58 13 04

• You either do it by replacing it (Ctrl + R), or by simply searching and copy-pasting the new value over
• Now, press Ctrl + S to save the file
