Here is an All Item Code minus the key items for DQ8 USA or EUR. You have to use them one at a time (don't turn on both codes at the same time). I used one, went back to game, then went back and turned it off and turned the other one on. After it registers, you can turn the codes off so you can sort the bag.
Code:
[All Items In Bag (Minus Key Items) 1]
D5000000 00000001
C0000000 0000013A
185369DE 00000050
D7000000 085369DC
DC000000 00000002
D4000000 00000001
D1000000 00000000
[All Items In Bag (Minus Key Items) 2]
D5000000 00000163
C0000000 0000004B
18536EC6 00000050
D7000000 08536EC4
DC000000 00000002
D4000000 00000001
D1000000 00000000
In this process, I came up with the Hex for items in DQ8. It is attached if anyone wants it.
