How to edit the items on the floor in BW2

[AC_Zepp]

Okay this question may have been answered already but I just can't seem to find it anywhere, sorry if that's the case.

The question is pretty much what the title says: How do I edit the items that are on the floor in BW2? Are they in some NARC file, if so which narc is it?

I have tried to find them on some narcs (narcs related to overworlds, maps, etc) but I haven't been able to find 'em.

I am fairly used to edit stuff with HxD, so please tell me how do I edit those items via Hex Editor?

They're part of the scripts.

They essentially "give item", delete the overworld then set a flag to prevent spawn.

So you mean that the data of those items is stored within the script narc (a/0/5/6)??

[Kaphotics]

Correct.

Well since you said it's there I assumed that the data for an specific item (say TM46 Thief, it's index number being 0x0175 in hex) would be within the script of the location in which that item is found (in this case that's the Virbank Complex, file 914 of narc a/0/5/6), and that I would find a 'give item' script for that item in there but I couldn't find any trace of that item's index number in the file, what am I missing??
