Hello there currently I'm playing Radiata Stories on pcsx2 v1.4

I managed to find the address for STR, which is capped at 999
the adresses however are 2byte and 4 byte, and no matter how high I set them to, the ingame stat stays at 999.

Is there any possible way to break the cap? For this game, or for any game at all?

Thanks!

Find out what accesses the value.
Increase the number.
Identify the code that checks if it is over 999.
Set the cap there to whatever.

Right-click on the STR value and check to see what is accessing it. The debugger window will pop up and should populate with some results. Let it run for a second, then change the STR to something that exceeds 999. Watch the debugger window to see if any new instructions populate the list when you do this.

That is because the normal process of writing the value already does a value check, There will be something that compares and jumps based on a value, break and trace the entire function (before your write, this means break and trace from the write, find the ret, double click the line below the first "ret" In memory viewer, go one instruction up (this is the function that called it) break and trace again, now scroll through the code until you see a compare against 100 (64 hex), change the 100 to 999, force it to always take the jump, or w/e you feel like, there are 100s of ways to get your results.

You're just going to have to look at the code around the instructions to see where the compare is being performed.

Since you don't know what is actually being compared, you'll have to keep that in mind. For example, 100 may or may not be what is compared against (it could be 101, which is 65 in hex).

good observation, it could be

> 99, set to 100
> 100, set to 100
>= 101, set to 100

It could also be something else too, depending on their creativity.

so for 1 stat (Leadership), I figured out I have to change 2 instances of comparison.

cmp eax,64
mov ecx, 00000064 ---> I changed it to 000000FF
cmovg eax,ecx
|
|
| } some other codes
|
|
cmp ecx,64
mov eax,00000064 ---> I changed it to 000000FF
cmovg ecx,eax

and then I set the value of the stat to 255, and it shows as 255 in-game
BUT only in the info page (that means the actual stat stays 100 and doesn't do shit)

if I go down after that, I will find the exact or similar rows of codes, for the other (next) stat, which is WAR (There are LEADERSHIP, WAR, INT, and GOVERNANCE)

any idea why the actual stat doesn't change?

Many,

There is a check when the stat is applied;
There is a formula for stat effects, this formula is maxed out when a stat is 100;
The Stat page is only a display page, so you found how to edit the display of the values but not the values themselves (where ever they may be)

just keep looking, you will find it, it cant be hidden, your image you added shows that you changed the visible value of the page, not the stats, find the stats compare

Why dont you do a replace all for the whole game:

Replace: 0F 4C CA 83 F9 64 7F 0F
With: 0F 4C CA 83 F9 FF 7F 0F
