I guess you confused something there.
The "Original file" when decompressed returns a file containing strings like "BOSS" and other strings.
While the "Decompressed file" is a totally different file (the one of your screenshot) which is encoded in base64, when decoded you can see a hexadecimal string and various bytes.

Hi Aluigi,
I use this script: http://aluigi.altervista.org/bms/bmscrypt.bms
Maybe the scripts encode the file after decompressed. Can you give me your script you used ? Thanks

Offzip, drag'n'drop csv.bytes on offzip.exe and it will be decompressed automatically.
