    Move the item table from 0x3DB028 to free space. Should be (375 items)(44 bytes/item). Repoint all pointers to it. Do the same for image and palette pointers at 0x3D4294, except entries are 8 bytes each (4 for each of them).

    Code: 
    .equ item_limit, #0x___ //CHANGE TO ITEM LIMIT

.org 0x09A8A4:
	lsl r0, r0, #0x10
	lsr r0, r0, #0x10
	ldr r1, =item_limit
	cmp r1, r0
	bge return
	mov r0, #0x0
return:
	bx lr
.pool


    @0x098998:
    Change word to new number of items.

    I'm guessing you already know this, but I'm quoting you just in case. I happened to be attempting to expand items in a test ROM and failed when I followed my own directions from this thread :P If you directly followed what I said, you probably would have had image errors for items beyond ~188. When I first expanded items, I made a little notepad file. I very intelligently wrote "img pal pointers" instead of the far more useful "image AND palette" pointers. So that second table is actually 8 bytes for each item. Hope that didn't cause issues! I've amended my earlier post.

    Actually, I never knew this, I just wanted to know how.
