I wasnt able to decode it but I made a bypass to use 0.40 password.4.1 gallery code?
bypass only works with included file!
1) extract zip "gallery bypass" to base game dir
2) "brownheart" will then work for the code
unnecessary but here are backup instructions if the real code gets released:
if you do not have an extracted game you can revert back to stock by deleting the file \game\gamemanagers\gallerymanager.rpy
if you have an extracted game you can use the backup file to revert back if you want
