No you can not access the memory directly like that.
Why you need it?

He's probably trying to make a game trainer, i know you can do things like that in C++ i also thought you could do it in Pascal?

In modern OS it's not a good idea to access memory directly.

Anyway I didn't test it but may be this works.

Code: [Select]

VAR
  MyPointer: ^BYTE;
BEGIN
  MyPointer := POINTER ($23456D...);
  MyPointer^:= 59;
END;

Are they still working that way? I thought they modify data files nowadays.

That code make Access Violation in protected systems.

I've never done it myself but I saw such code in Delphi.
IMHO it still should be possible on modern systems. After all, a lot o game hacks operate on accessing memory (yes memory, not file).

For example StarCraft hacks. I saw hacks to this game made in Delphi and Visual Basic I think it could be possible in Free Pascal too. Probably by using Windows API. Don't know hot it works under Linux. But it is certainly possible under Windows.

trainers just modify the memory, while most other hacks will modify data files.
Trainers are patched fairly easily and often, other hacks will inject .dll's into the game and gets to call functions etc.
I don't know how to make one, just got a general idea how they work.

Thanks for the explanation, MuteClown.
