Weapon Order

Your three gear order save slots are at 0x12CDCD00-0x12CDCDBF:

Each slot is sixteen integers (of 4 bytes) long, so sixty-four bytes in total:
1 integer (4 bytes): Gear type (0x00000000 = Shoes, 0x00000001 = Clothes, 0x00000002 = Hat)
1 integer (4 bytes): Gear identifier. For the IDs, see the following: Shoes: http://pastebin.com/mX8yqMg4 Clothes: http://pastebin.com/cket483N Headgear: http://pastebin.com/G9viKdFs
1 integer (4 bytes): Number of abilities leveled (in battle, 1=only main, 2=main + 1 sub, 3=main + 2 subs, 4 = main + 3 subs.)
1 integer (4 bytes): Number of ability-slots unlocked (by Spyke, 1=only main, 2=main + 1 sub, 3=main + 2 subs, 4 = main + 3 subs.)
3 integers (12 bytes): IDs of sub abilities
1 integer (4 bytes): Experience points of gear
1 integer (4 bytes): Unused. It is set to 0x00000000.
1 integer (4 bytes): Unix-timestamp of your order time.
1 integer (4 bytes): Unused. It is set to 0x00000000.
1 integer (4 bytes): Unix-timestamp of your time of arrival of the gear.
1 integer (4 bytes): Some kind of identifier associated with the guy you ordered the gear from.
1 integer (4 bytes): Unused. It is set to 0x00000000
1 integer (4 bytes): Slot-free-marker. If you cancel or collect this order, then it is set to 0xFFFFFFFF. Otherwise it reads 0x00000000.
1 integer (4 bytes): Unused. It is set to 0x00000000

An unused save slot looks like this:
FFFFFFFF FFFFFFFF 00000001 00000002 FFFFFFFF FFFFFFFF FFFFFFFF 00000000 00000000 00000000 00000000 00000000 00000000 00000000 FFFFFFFF 00000000
