yea, well the freeze code is 5 for the 0 slot backpack, 6 for the 1 slot, and 7 for the 2 slot, if you dont freeze the slot count like you did (5)
the standard backpack is 7001 and the advanced is 7002 (1b59 and 1b5a, or in wpe they show up reversed so 591b and 5a1b)
cant seem to get the value for the santa bag though, i thought it might be 7007 but it wasnt. same for the 3/4 slot bags.
Whenever I search for 2 after I equip the advanced backpack I get "No results found; Previous search restored." I've tried it many times already and tried searching 255 and repeating after it gave me that message. Anyone able to help me? Thanks.
