Rocket League Xbox One Files (.xxx)

« on: April 26, 2025, 23:41 »

I've been looking into trying to get the Xbox One files of Rocket League working, i personally lack the experience in coding knowledge to do this, i have had the few people that i can find that have knowledge with UPKs / Rocket League they have either moved on or just don't have the time

UModel (UE Viewer) doesn't have any support for Xbox Ones games as they have been unobtainable for a long time, there was recently method figured out around August/July so games are now dump able from that console platform

I imagine alot of the games already that are UE3/UE4 based on Xbox One have PC Counterparts so there isn't much to worry about in that regard

Rocket League is available on PC/PS4/Switch, PC and PS4 are already viewable on UModel (PC to specific version), i want to try and preserve the console exclusive cars / exclusive files as the PC version doesn't have them

The Xbox Files are slightly different from the PS4 versions, the PS4 version seems to be completely unencrypted (plain text) the older versions, the xbox files are encrypted i believe as viewing in it HxD after first few bytes its just randomized

I'll upload two versions of files from different revisions of the game, ones from launch on Xbox One and ones from an update in August

The file sizes increase but they're the same car (i imagine this is console of the texture upgrade the xbox versions got in a later revisions?) the later one has a structure tree in full text via hex editing unlikely the first one

Folder containing the files from different versions - https://mega.nz/folder/79lEyLaC#0EfibHm2Qc9oyVeUuJlS4w

I've marked them as 1.0 and 1.1.4.3 respectfully

I was able to dump AES Keys from 1.0 and 1.1.4.3 Thanks to help from Stev and another user in the Rocket League community I don't know if i'm allowed to post them publicly but i can provide them if that is allowed

Thank you for taking your time to read this and i appreciate if anyone has any help or advise thank you

@Techo: Xbox One version is not encrypted either, just compressed. You can use specific umodel build from this topic with game specific override and respective platform option to load provided samples. Though only earlier version works properly, more recent update has various inconsistencies in packages (some offsets are a few bytes off and some are pointing to the middle of nowhere, and it's different between packages). Considering that PS4 version is using even newer version than provided update (PS4 = 32, Xbox = 31) and works fine with the mentioned build, the only reasonable explanation is that data was corrupted upon dumping. Materials are not loaded properly in recent PS4 versions though.

Thank you for doing this so much, there is a possibility the newer build is corrupted i know Rocket League changed stuff about internal files wise in later revisions

The models were able to load fine when i tested them

I'll see if i'm able to upload the Switch files of Rocket League in the future as that would be great to have support wise in the future

EDIT: Found a folder i had with some of the files from the switch version awhile back https://mega.nz/folder/PxkUjASI#GKxi87pwkhpHbkIY5meteg

@Techo: I've updated specific build, it should work with all console versions of the game if they're not encrypted or using default key. Newer Xbox One versions also should be supported except for actually corrupted packages (like Body_SweetTooth_SF from samples). Also latest Switch versions are using the same approach as PC version with multiple keys, but packages with default key should work.

@spiritovod : Yep i can verify it works on the newer xbox version as well now interestingly the "GearCar" wouldn't get its materials applied in 1.0 but it works fine in the later version it complains about not being able to find it but the .tfc has the textures inside of it from what i saw

All banners and other textures seem to work as well now outside of any corrupted ones

Thanks for all the help Spirit

@Techo: If you mean "tfc file is missing" warning, apparently Xbox One version is using separate texture caches, while in PS4 and Switch versions they're mostly clamped into "textureNUM.tfc" files. Though it just means you don't have respective file(s) in the same folder with the package producing such warnings.
