  2. ReadWriteMemory



This is a helper library for reading and writing memory to both 32-bit and 64-bit processes in Windows. Many versions of Windows are supported, as long as they have a usable version of kernel32.dll.

NOTE: This library does not help you aquire offsets.

You can use it like this (a sample Visual Studio project is included)

class Program
    static void Main(string[] args)
        var RWM = new ReadWriteMemory64("notepad");
        if (!RWM.OpenProcess(MemoryHelper.GetdwDesiredAccess()))

There is also support for writing/reading different types depending on memory offset.

  • Float
  • Int
  • Byte
  • Double
  • Short
  • Unicode string
  • ASCII string


  • Include a memory scanner.
  • Figure out a better system for int/long conversions to reduce duplication between 32 and 64-bit classes.
