Replace Item with Shared Item

Replace Item with Shared Item

This code will replace an item that you receive from the roulette, to one of your choosing. I originally created it to avoid getting Thunder Clouds. It is undetectable if the item replaced is one that can legitimately be received in your current position.

Good stuff. So its like Replace Item code but based on Shared code instead of Forced. Has this been tested against CTGP IIB? If not and you end up testing it and it fails, try using Anti-Item spy equipped.

Correct. Just as the original Shared Item code, as long as the item replaced is a probability in the position, it is undetectable. The clans I have played against can vouch for that ;-).

Updated to support both single and multiple items.

Have you tested the multiple item version? And can the single item version be used multiple times in a GCT (I ask this because of the limitations with the Forced-based Replace Item Code)

Yes, the multiple item version works as expected.
No, the single item version cannot be used multiple times in a GCT. The reason being is that it will overwrite the branch address each time it is added. You can see this in WiiRD.

The instruction is replaced:
807B97D0: 4B8490F8 b 0x800028c8

However when I apply the code again:
807B97D0: 4B849118 b 0x800028e8

The first code is still in RAM, but since the branch address is updated to the latter code, only that will be executed.

For those who are wanting to use this code, it's best imo to run it without any activators/deactivators.

Updated the multiple items version to improve performance. It still functions identical to the original version. The only difference is it will store the item immediately when it reaches your current item, rather than redundantly checking the rest of the items.
