I edited IFF via FileXplorer, and even noticed stuff I didn't notice in the hex editor. I made a thorough edit; no mistakes were made here. I double-checked to make sure all the required textures, MPETs, and icons were in the to-be-packed data folder.
I repacked the PAK, replaced the login/game server IFFs, corrected any changes in the PANGYA_ITEM_TYPELIST table, and ran the game. It started up; so far so good.
Logged in, and checked the shop: It's not there.
Alright, how about the /giveitem command?
Code:
GM_Command:/giveitem miku 136331368
TypeID : 136331368, Item Name : Dealer Vest B (Lucia), Quantity : 1
Would you like to give the following item to 'miku' [/y, /n]
GM_Command:/y
Items have been granted.
Awesome. I go to check my inventory: ... Nothing. There's no entries in the Pangya_Item_Warehouse, either.
Not a clue what I'm doing wrong now.
UPDATE: I added the items manually via Pangya_Item_Warehouse, and they are in my inventory now in perfect working order.
Now I just need to figure out why they won't appear in the shop, and why /giveitem doesn't work.
