Advice on how to increase running speed of playable character in PS2 game(s)

[Shademp]

In the PlayStation 2 version of Castlevania: Curse of Darkness I wish to find addresses for changing Hector's & Trevor's running speed. Using Cheat Engine I have only been able to increase their speed while they are jumping, in free fall and/or knocked back by an enemy.

Video:

If I could adjust the running speed for while the playable character is grounded then I could create MUCH better videos showing off the game's test maps.


The 4-byte address I use for increasing the free fall speed [20B0412C, North American version] actually tracks Hector's speed at all times. Expressed as floats:

Walking speed: 3.703703642
Running speed: 18.51851654

I have spent dozens of hours looking for potential values, be they changing or static, and potential memory regions that might determine how much distance is traversed per directional input. I have come up empty and am now looking for advice on how to proceed. Any help or even just brainstorming is appreciated!

Create a memory dump and use the ps2dis instead or pcsx2dis. Find a code that was previously hacked for this game such as a health code. In that function you will see a pointer that will be loaded, it is easy to assume this will be your player pointer. navigate to where your player pointer is pointing and go through the player object while moving. In most game you will find a float value for all types of character movement.

The 'player speed' address can be under the value '3F800000' For example: Resident Evil 4, Ghost Hunter, but not all games. In this case this is the case... Here are the codes I used for testing, but the whole game did not pass ....
