[FR/EM]Show item image when it added to the bag

~Andrea said:

Good morning!
These days i saw an update of an Italian hack, where there was a very interesting feature, that is the loading the image of items when they added to the bag.
Since it seemed like a nice thing to implement in our ROMs, today i'll explain how to do that!

# 1 - Hook and Routine asm

FIRE RED:

Spoiler:

Let's get to the offset 080F6F08 and overwrite bytes with 00480047XXXXXX08Instead of XX the offset of asm routine will be inserted in little endian.

EMERALD:

Let's get to the offset 081973E8 and overwrite bytes with 00480047XXXXXX08Instead of XX the offset of asm routine will be inserted in little endian.
Next, go to the offset 08099738 and overwrite the bytes present with 00 00.

Next we compile the following routine in a free offset within the rom:

In the asm routine, there is a red istruction:

Put 1 if you want the routine will be compiled for emerald, otherwise leave 0 if you want the routine works on red fire.

Important notes:
- it's not compatible with Jpan's Hacked Engine, for now
- The routine works only with the type message 1 (MSG_FIND) of the giveitem:

its late but i figured out a mistake that was screwing up some of the roms. instead of xxxxxx offset should be inserted in little endian + 1. now it works for me .
