Hi all, I got a problem.
Why can't I sometime freeze an adress ? and I also can't modify the adress's value from the memory viewer :s but I can only from the main windows by editing the value option.

Can you explain me why please ?
Edit: Oh well, it's a read only memory, so how CE does to change the value please ?

Well, I'll try to more explicit so.

I need to change the value of an address which is a read only address(ROM).

It's possible to edit its value with CE by editing its value in the value collumn like this :

But from the memory viewer, I can't change its value :S.

I explain me : I use CE to make trainers in delphi, but I don't have any idea of how to poke an address in read only.
But it's possible to edit it in Ce as I said before, so I just wanted to know how it was working =).
Thx

Is that the address from an instruction?

Go back into the memory viewer, count its bytes, go back out change it's type to an array of bytes. NOP it by changing all the bytes to 90. Do remember what it was before though, so you can undo the NOP.

I don't really Have understood what to do :

I have my adresse which is a text : "GLB:"
So 4 caracters, so I should choose 4 bytes for the array of byte no ?

But I want to change it's value to "SYS:"
So I don't understand, cause I just need to change it to a writable memory or smt like this :s.

Could you explain me what you mean by changing my array of byte with my byte in "90" ?

Cause I think it won't help me, or maybe I don't have understood ^^.

Thx

Go here and read up on using DB.
This will help you change what you want in Bytes.
Then you can make a trainer.

Good luck

Well I've understood that this adress was in read only.

I can modify it in asm like this :

[ENABLE]
64D60C:
db 53 59 53

[Disable]
64D60C:
db 47 4C 42

But I don't how how to do this in delphi :S Very Happy

Try asking in the programming section about writing it in delphi.
