New discovery:
Blade = 06 00 00 00 00 00 00 00 FF FF FF FF
Katana = 06 00 00 00 01 00 00 00 FF FF FF FF
Orb = 05 00 00 00 00 00 00 00 FF FF FF FF
Crystal = 05 00 00 00 01 00 00 00 FF FF FF FF
So maybe changing 06/05 is not the only thing we need to do... maybe for working dupe of other item, we need change other thing too in this region.
Edit: Some item can't be found by searching their name, because text is not always correctly displayed in memory view. For example, you can't find great sword. but the second item always come before the first in memory view, ex. Daikatana, which is 07 00 00 00
01 00 00 00
will come before Greatsword, which is 07 00 00 00
00 00 00 00 . So to find for example the Forcium Great Sword, in memory view, "search memory...(it's that when you right click in the memory view. in "Search" on top(after file), its named "find memory"". Search for "(Array of) Byte", then search for "07 00 00 00 01 00 00 00 FF FF FF FF". Search until you found a sequence of those in memory view. those are all the Daikatana, in order. Go down in the memory view until you find it's now "07 00 00 00
00 00 00 00 FF FF FF FF" Instead. You are now in the Great Sword memory region, and the last one in that region will be Forcium Great Sword ;)
