Just a simple money editor here. You can use the information here to extend your hack into something brilliant.
What you'll need- Microsoft Visual Studio. I'll be using 2008 edition in this tut, so don't expect the steps to be exactly the same in a different edition. I will not provide you with download links, so don't ask me for them.
- GTA:SA Memory Addresses
Getting StartedStart your new project and give it a name. Make sure you choose
Visual C# -> Windows Forms Application.
You'll then get your blank program. Open up your toolbox and drop a button onto it. Use the Properties box to call it whatever you want.
Double click on the button to open the code window.
To get the hack working, you must paste this code into the program:
// C# Signature for the FindWindow() API
[DllImport("USER32.DLL")]
public static extern IntPtr FindWindow(
string lpClassName,
string lpWindowName
);
// C# Signature for the WriteProcessMemory() API
[DllImport("kernel32.dll")]
static extern bool WriteProcessMemory(
IntPtr hProcess,
IntPtr lpBaseAddress,
byte[] lpBuffer,
UIntPtr nSize,
out IntPtr lpNumberOfBytesWritten
);
// C# Signature for the OpenProcess() API
[DllImport("kernel32.dll")]
public static extern IntPtr OpenProcess(
UInt32 dwDesiredAccess,
Int32 bInheritHandle,
UInt32 dwProcessId
);
// C# Signature for the GetWindowThreadProcessId() API
[DllImport("user32.dll", SetLastError = true)]
static extern uint GetWindowThreadProcessId(
IntPtr hWnd,
out uint lpdwProcessId
);
// C# Signature for the ReadProcessMemory() API
[DllImport("kernel32.dll", SetLastError = true)]
static unsafe extern bool ReadProcessMemory(
IntPtr hProcess,
IntPtr lpBaseAddress,
void* lpBuffer,
int dwSize,
out IntPtr lpNumberOfBytesRead
);
Place it all under the line that says "
public partial class Form1 : Form {"
You can now make a function that edits the program memory using the above system functions. Here is one I made for your personal use:
public static bool EditMemory(int Address, uint Value)
{
UInt32 ProcID;
IntPtr bytesout;
IntPtr WindowHandle = FindWindow(null, "GTA: San Andreas");
if (WindowHandle == null) { return false; }
GetWindowThreadProcessId(WindowHandle, out ProcID);
IntPtr ProcessHandle = OpenProcess(0x1F0FFF, 1, ProcID);
WriteProcessMemory(ProcessHandle, (IntPtr)Address, BitConverter.GetBytes(Value), (UIntPtr)sizeof(uint), out bytesout);
return true;
}
You can use this function to edit your money. The address for money is 0xB7CE50, so you can edit your code to look like this:
private void btnMoney_Click(object sender, EventArgs e)
{
uint money = 99999999;
EditMemory(0xB7CE50, money);
}
If you're not very computer fluent, this sets your money to 99999999.
There's one more step you need to get your hack to work. In the menu bar, select "Project -> <YourHackName> Properties". On the Build tab, the "Allow Unsafe Code" check box
must be checked.
I haven't tested this program, but it should work properly. Hope you've enjoyed this tutorial.
