Custom Modifications (Standard)

This page aims to educate users on how to change whatever values they want in their game.

When you're modifying data during gameplay, you're actually modifying the data in your RAM.
Hence, we'll be referring to Gold & Silver's RAM MAP, which is this page.
Anything, ranging from Pokemon's DVs, to Shininess, to items, all that data can be found there.

Box Name 1 data structure
This is what it typically looks like:

The address and value is converted from Hexadecimal to Box Name Encoding,
via this table below (in the spoiler):

Example on data modification
Step 1: Find the new name needed for Box 1
This example is regarding changing the first ball in your bag's Ball Slot, to Master Balls.

According to the ram map, this is the data address for the 1st Ball slot:

$D5FD = Ball 1
$D5FE = Amount

Now, the aim is to change 1st Ball Slot to Master Ball.
Here's a look at what it is, before the change.

Now, as per Data Structure, we need to change the address $D5FD (also commonly written as 0xD5FD) to the Box Name Encoding.
First, we search for 0xD5 in the table. We will see that 0xD5 -> 'v9

Next, we will search for 0xFD on the table. We will see that 0xFD -> 89


Lastly, we know that we are changing the Item to Master Ball. We will see that Master Ball -> AB


So the new name we acquired for Box 1, is 'v989AB

Step 2: Change Box 1's name

Step 3: Use TM17 that is in Item Pocket

Step 4: Check if change was made!
Following our example, it became Master Balls!

Once you want to make other changes, just run through Step 1 to 4 again.

For example, if you want to change the amount,
Restart from Step 1, with $D5FE as the focus this time.
