I just asked about meaning of the error. UModel attempts to open file "Kingdomhearts31.pkg" in the folder "C:\Users\kinse\Desktop\Kindom Hearts 3 Rip" and throws an error because the file is larger than (to be more precise, EXACTLY matches) 4Gb size.
If you want to know anything else about the game support, you should refer to the main game's thread - use compatibility table or forum search to locate it.
Alright, thank you. I checked the files size and it is 4 gb. Do you know how to solve this size issue? Like, is there a way to trick it into thinking it’s another size? Thank you for your help so far, by the way, it means a lot!
