1. Download modded file with the link provided in the video above
2. Go to the MK10 folder where the game is located. For steam users the directory is commonly in C:\Program Files (x86)\Steam\SteamApps\common\MK10.
3. Go inside the MK10/Asset folder and scroll down to find ui_c_buttonLib.xxx
4. Reccomended: Make a backup of the original ui_c_buttonLib.xxx and put it somewhere safe and you can come back to if things go wrong or you want the Xbox buttons again
5. Replace modded/downloaded ui_c_buttonLib.xxx into the Asset folder
6. And BAM you should successfully have changed from Xbox buttons to Playstation buttons in Mortal Kombat X
