Hey Guys,

I just decrypted the Nintendo Switch Game "Fortnite" and wanted to extract and probably rebuild the pak I just extracted from the Game.

I've tried the unreal_tournament_4.bms to extract the pak-file ( http://zenhax.com/viewtopic.php?f=9&t=1005 ) without luck.

I'm getting this error:

select the BMS script to use. type ? for using the clipboard
- select the input archives/files to extract, type * or "" for whole folder and subfolders
- select the output folder where extracting the files
- open input file I:\Nintendo Switch\Fortnite Update\romfs\FortniteGame\Content\Paks\FortniteGame-Switch.pak
- open script I:\Nintendo Switch\Fortnite Update\romfs\FortniteGame\Content\Paks\unreal_tournament_4 (1).bms
- set output folder I:\Nintendo Switch\Fortnite Update\romfs\FortniteGame\Content\Paks

offset filesize filename

result 0xffffffffffffffff -1

Error: the uncompressed data (-1) is bigger than the allocated buffer (7404)

Last script line before the error or that produced the error:
194 clog NAME CHUNK_OFFSET CHUNK_ZSIZE CHUNK_SIZE

Using u4pak.py gives me this:

u4pak.py info "I:\Nintendo Switch\Fortnite Update\romfs\FortniteGame\Content\Paks\FortniteGame-Switch.pak"
unsupported version: 6

So it seems the file is somehow compressed and uses UE4 PAK version 6?

Could you help me out with that?

I want to extract the files and, if possible, rebuild it / replace files.

EDIT:
Here's the file:
