I made a game a while back in UE4. It was packaged and but didn’t generate the uProject file but anyway, I lost the Project files and only have the packaged build. Is there a way to use that build to reimport it into UE5 or an older UE4?
This is a personal project game I should add, I made it in a game jam in 2020.
Hey there @willem567! Without the project files, it would be difficult to recover everything. The simplest things you could rip out would be mesh or texture assets. Blueprints or code is next to impossible to cleanly take once compiled. If you have access to your pak files and have the engine version installed you should be able to unpack them using UnrealPak.
(This is assuming you never encrypted your pak files)

De-compilation or memory reading isn’t so straightforward, nor would it get you outright usable code. My recommendation in this case would be since it’s a jam game, just retrieve your art assets and rewrite it. Since it was a jam game it’ll likely take significantly shorter time and effort wise to rewrite than to try and decompile and reverse engineer your bindings.
