Do these only work while in the locker? I tried it just in a mission and it didn't change the costume so i'm guessing it simply "unlocks" the costume with the cheat and you have to put it on to actually wear it.
In any case thanks for codes!

This is a super rough translation but on 91wii someone else who posted astral chain cheats explained why the item codes don't always work and how you can make them work.
"The order of all the items in each player's game is not the same, please use 0a2fbaa8 which is encoded by common elements, and calculate the position offset to convert hexadecimal. My own The [luxury element code 9999] 04000000 0a2fbb00 0000270F. For example: the second column of the common element code is 0a2fbaa8 conversion decimal value is 170900136, into the game press -, view all props, luxury elements ranked 11th in the common element code Position, so hexadecimal operation plus 11*8=88,170900136+88=170900224, conversion hexadecimal is 0a2fbb00, ie [luxury element code 9999]04000000 0a2fbb00 0000270F + H3 g.
