Unpacking blank file? [NCAA 14]

Post by maizeblue11 »

I have a blank file I need to unpack to find it's textures and don't know how to. In the hex I see XPR2 and MC02.

File link: https://nofile.io/f/J7H9YztzB7r/TEAM-001

Name of the game?

Try this:

Code: Select all

endian big
idstring "MC02"
get ARCHIVE_SIZE long
get HEADER_SIZE long
get DATA_SIZE long
goto 0x2c
get FILES long
xmath OFFSET "ARCHIVE_SIZE - DATA_SIZE"
for i = 0 < FILES
    get SIZE long
    log "" OFFSET SIZE
    math OFFSET + SIZE
next i

It worked, but the XPR files are both unreadable: Image

Here is another file I wanted to unpack: https://nofile.io/f/BJjEdKdnpZY/TEAMBUILDER-LIBRARY
