HPD v2.0 for PS2 Customization Corner

HPD Customization Corner

Introduction
Before we begin a little test:
20 equals 0x14,
If we can agree on that let's continue.
Otherwise you might want to familiarize yourself with the hexadecimal system first.

Chapter 1
Changing the default start-up behaviour.
Near the end of the 2nd Part you can find the following lines.
If you have trouble finding them search for the only line that starts with a 1

Code:

[CENTER][SIZE="4"]
[COLOR="DimGray"][SIZE="1"][...][/SIZE][/COLOR]                                               
[COLOR="Silver"][COLOR="DarkGreen"]1[/COLOR]00F87F2 00000101                                 
200F87F4 80012001[/COLOR]                                 
200F87F8 [COLOR="Blue"]10000021 [/COLOR]   [COLOR="Blue"]hackOff[/COLOR] (Never change this!) 
200F87FC [COLOR="RoyalBlue"]20100000[/COLOR]    [COLOR="RoyalBlue"]hackOn[/COLOR]  (Never change this!) 
200F8814 [COLOR="Red"]10000021[/COLOR]    [COLOR="Red"]default behaviour[/COLOR]            
[COLOR="DimGray"][SIZE="1"][...][/SIZE][/COLOR]                                               
[/SIZE][/CENTER]

Now use the two blue parts as an example (don't change them)
Instead change the red part in the last line to one of those values
As you can see it currently is off by default.

Chapter 2
Changing the default button combos.
Directly above the the lines from the last chapter you can find this

Code:

[CENTER][SIZE="4"]
[SIZE="1"][COLOR="DimGray"][...][/COLOR][/SIZE]                                                        
100F87F2 0000[COLOR="Purple"]0101[/COLOR]    ButtonCombo:  [COLOR="Purple"]De/activate Hack[/COLOR]        
200F87F4 [COLOR="Blue"]8001[/COLOR][COLOR="Teal"]2001[/COLOR]    ButtonCombos: Scroll theme [COLOR="Blue"]left[/COLOR]/[COLOR="Teal"]right[/COLOR] 
[COLOR="Silver"]200F87F8 10000021                                          
200F87FC 20100000                                          
200F8814 10000021[/COLOR]                                          
[SIZE="1"][COLOR="DimGray"][...][/COLOR][/SIZE]                                                        
[/SIZE][/CENTER]

Change the colored values to the buttoncombos you prefer.
You may use this picture as a reference if you don't know the
appropriate values for each of the 16 available buttons.

Chapter 3
Creating a custom theme.
A theme for this hack looks like this:

Code:

[CENTER][SIZE="4"]
E00[COLOR="Blue"]9[/COLOR]00[COLOR="Green"]01[/COLOR] 000F87EC    if([COLOR="Green"]ID==1[/COLOR]){execute next [COLOR="Blue"]n[/COLOR] lines} 
[COLOR="RoyalBlue"]200F8820 240400[COLOR="DarkOrange"]00[/COLOR]        [COLOR="DarkOrange"]txtColor (White)[/COLOR]            
200F8824 240500[COLOR="DarkOrange"]12[/COLOR]        [COLOR="DarkOrange"]txtHeight[/COLOR]                   
200F882C 240400[COLOR="DarkOrange"]12[/COLOR]        [COLOR="DarkOrange"]txtWidth[/COLOR]                    
200F8830 240100[COLOR="DarkOrange"]0E[/COLOR]        [COLOR="DarkOrange"]txtPosY_offset[/COLOR]              
200F8838 24A5[COLOR="DarkOrange"]0078[/COLOR]        [COLOR="DarkOrange"]txtPosY[/COLOR]                     
200F8840 2404[COLOR="DarkOrange"]0018[/COLOR]        [COLOR="DarkOrange"]txtPosX[/COLOR]                     
200F8944 [COLOR="DarkOrange"]253A7325[/COLOR]        [COLOR="Orange"]String:"[/COLOR][COLOR="DarkOrange"]%s:%5d/%d[/COLOR][COLOR="Red"]\0[/COLOR][COLOR="Orange"]"[/COLOR]        
200F8948 [COLOR="DarkOrange"]252F6435[/COLOR]                                    
200F894C 0000[COLOR="Red"]00[/COLOR][COLOR="DarkOrange"]64[/COLOR]        [COLOR="Red"]zero terminated!![/COLOR][/COLOR]           
E001FEFE 000F87E8    if(initPhase)                   
30200001 000F87EE        maxThemes++                 
[/SIZE][/CENTER]

Let's focus on the (green) themeID first: The ID must always be ascending.
Meaning: The first Theme must be 1 unless you are also using a Theme Pack.
In that case check the last ID of the Pack and continue from there.
Next we have the blue lines. Each with a different purpose.
Simply change the orange parts in each blue line you want to adjust.
If you always keep/change all lines you will only have to adjust the line amount
based on the string length. But there is also the possibility to shorten the theme.
You can always reduce the theme to the actual lines that you made changes in.
i.e.: if you just want to change the color:

Code:

[CENTER][SIZE="4"]
E00[COLOR="Blue"]1[/COLOR]00[COLOR="Green"]01[/COLOR] 000F87EC    if([COLOR="Green"]ID==1[/COLOR]){execute next [COLOR="Blue"]n[/COLOR] lines} 
[COLOR="RoyalBlue"]200F8820 240400[/COLOR][COLOR="DarkOrange"]02        txtColor (Red)[/COLOR]              
E001FEFE 000F87E8    if(initPhase)                   
30200001 000F87EE        maxThemes++                 
[/SIZE][/CENTER]

If you use multiple themes that change different aspects it might be
a smart choice to include lines you change in one theme in all the other themes.
(check how the default ThemePack modifies the string)

Chapter 4
Making your own Theme Pack.
If you end up with a set of themes you might want to group them to a themePack
In that case just add them together and remove all but the last init Phase Checkers
The last maxTheme++ must then be changed to add the amount of themes in the pack.

Code:

[CENTER][SIZE="4"]
E00[COLOR="Blue"]1[/COLOR]00[COLOR="Green"]01[/COLOR] 000F87EC    if([COLOR="Green"]ID==1[/COLOR]){execute next [COLOR="Blue"]n[/COLOR] lines} 
[COLOR="RoyalBlue"]200F8820 240400[/COLOR][COLOR="DarkOrange"]01        txtColor (Black)[/COLOR]            
E00[COLOR="Blue"]1[/COLOR]00[COLOR="Green"]02[/COLOR] 000F87EC    if([COLOR="Green"]ID==2[/COLOR]){execute next [COLOR="Blue"]n[/COLOR] lines} 
[COLOR="RoyalBlue"]200F8820 240400[/COLOR][COLOR="DarkOrange"]02        txtColor (Red)[/COLOR]              
E001FEFE 000F87E8    if(initPhase)                   
302000[COLOR="Magenta"]02[/COLOR] 000F87EE        maxThemes+=[COLOR="Magenta"]2[/COLOR]                
[/SIZE][/CENTER]

Chapter 5
Changing the default look.
There is a very simple way to change the default look within a theme.
You only need to modify the "initPhaseChecker".
Let's take the example from above and change it so red will be the default color.

Code:

[CENTER][SIZE="4"]
E0010001 000F87EC    if(ID==1)                           
200F8820 24040001        txtColor (Black)                
E0010002 000F87EC    if(ID==2)                           
200F8820 24040002        txtColor (Red)                  
E00[COLOR="DeepSkyBlue"]2[/COLOR]FEFE 000F87E8    if(initPhase){execute next [COLOR="DeepSkyBlue"]n[/COLOR] lines} 
[COLOR="Red"]000F87EC 000000[/COLOR][COLOR="DarkOrange"]02[/COLOR]        [COLOR="Red"]currentTheme = [/COLOR][COLOR="DarkOrange"]2[/COLOR]                
30200002 000F87EE        maxThemes+=2                    
[/SIZE][/CENTER]

Chapter 6
Changing the actual default look.
For those that have changed the look entirely it might be necessary, in order to keep the
themePacks small, to adjust the default values the hack uses stored in theme 0.
It is located at the end of the HPD, right below the parts from the first chapter of this guide.
You can change this theme like you would change a full custom theme.
But never try to remove any lines here. Unless you really want to crash your game.
Actually changing anything else besides the stuff pointed out in this guide, will most likely end in a blackScreen.

Chapter 7
Answering the last open question.
While reading Chapters 3-5 you might have asked yourself: "What is the initPhase?"
Well, as you should've read in the releasePost above, the hack only gets dumped once.
The moment the cheatEngine executes the region dependant part of HPD for the first time
the initPhase is triggered. It starts with the hack being dumped to RAM.
After this has happened the cheatEngine will go through each theme forcing them
to count themselves. Next the cheatEngine will do a full cycle until it reaches the HPD again.
This time the initPhase will be concluded by actually linking the hack into the gameCode.
From this point onwards the cheatEngine can only execute the
selected theme of the HPD in each cycle, the rest of the hack will be blocked by default.

Epilogue
Sharing your customizations with others
In case you want to publish the customizations you made to this hack, please do so here.
And while doing so please refrain from reposting the entire hack.
If you need to repost the last part because you decided to change one or all of the following:
theme 0/default status or default buttons.
Restrict it to the small piece that's start with the 1, (16bit write) [see Chapter 1]
and add a note, that it needs to replace the last part in order for your theme to function as intended.

And now after these walls of text and numbers:
