A tool for manipulating memory of external processes in Windows. Designed for debugging, game modding, or real-time application control, this utility enables you to write values in process memory safely and efficiently.
- Retrieve process IDs by their name.
- Write values to memory with support for multiple data types.
- Handles runtime type conversion for seamless integration with user input.
- GCC (MinGW recommended for Windows).
- Windows operating system.
To compile the project, use the following command:
gcc memory_editor.c types.c -o memory_editormemory_editor.exe <process_name> <module_name> <hex_offset> <type> <value>- process_name: Name of the process (e.g.,
ePSXe.exe). - module_name: Name of the module to locate (e.g.,
ePSXe.exe). - hex_offset: Offset in hexadecimal to calculate the target address (e.g.,
AF5424). - type: Data type of the value to write. Supported types (see the table below).
- value: The value to write to the specified address.
| Type | Description | Bytes |
|---|---|---|
"Binary" |
Used for binary values (0 or 1). | 1 byte |
"Byte" |
Used for small integers or single bytes. | 1 byte |
"2 Bytes" |
Used for short integers. | 2 bytes |
"4 Bytes" |
Used for standard integers. | 4 bytes |
"8 Bytes" |
Used for long integers or large values. | 8 bytes |
"Float" |
Used for single-precision floating-point numbers. | 4 bytes |
"Double" |
Used for double-precision floating-point numbers. | 8 bytes |
"String" |
Used for text values (variable size). | Variable size |
"Array of byte" |
Used for arrays of raw bytes (variable size). | Variable size |
.\memory_editor.exe ePSXe.exe ePSXe.exe AF5424 "4 Bytes" 16This command writes the integer value 16 to the memory address AF5424 of the ePSXe.exe module.
- Retrieves the process ID by name.
- Locates the base address of the specified module.
- Calculates the target address using the base address and given offset.
- Converts the provided value to the specified data type.
- Writes the value to the calculated memory address.
- Ensure you have the necessary permissions to manipulate process memory.
- Writing invalid values or to incorrect memory addresses can lead to application crashes or undefined behavior.
