I have been editing madden rosters since Madden 2008. This year they decided to encrypt it and im having trouble figuring it out. They are usually in DB file format. Hoping someone can help figure it out. Added a Madden 20 file for comparison. Thanks

Madden 21 PC roster file

Madden 20 PC roster file

This editor works with madden 19 and 20 files just use a hex editor to delete header to DB file then open.

I got an email about this new format one month ago and replied in this way:

Quote:

Yeah it's just zlib and indeed the format is totally different than the
one of the other sample.
This script is only in case you don't want to use offzip since I have
no idea regarding the content of the data.

###
idstring "FBCHUNKS"
get VER short
get HEADER_SIZE long
get ZSIZE long
savepos HEADER_OFF
get SIZE long
get YEAR short
get FLAGS short
if FLAGS & 1 # or year 2021
get SOME_CRC long
get FILE_SIZE long
math NUM = 8
else # or FLAGS & 8, or year 2020
math NUM = 4
endif
for x = 0 < NUM
get DUMMY short
next x
get NAME string
xmath OFFSET "HEADER_OFF HEADER_SIZE"
if FLAGS & 1
clog NAME OFFSET ZSIZE SIZE
else
log NAME OFFSET ZSIZE
endif
###

Basically you can just decompress the data with offzip -a but no idea how the decompressed data should be interpreted since it's not compatible with the format of the older version.

Here is an update from September 7 2020 about these files.
It seems that the first step to work with Madden 21 roster files is to figure out its format as it seems to be a new one relative to previous years. As aluigi said, you can decompress this Madden 21 file using offzip tool.
