Software DMA Implementation Example

This example demonstrates how to implement DMA (Direct Memory Access) using the MMapIOSpace function. With this approach, you can read any process's virtual memory without using handles, directly accessing physical memory.

Requirements

• BRD (Bring Your Own Driver): You'll need a custom driver if you want to make this work on other Windows versions.
• MMapIOSpace Drivers: These drivers work on Windows 10 with versions prior to 1803.
• Windows 11 Note: After Windows 10 version 1803, MMapIoSpace can only read unpaged memory. For Windows 11, you'll need to use ZwMapViewOfSection.

Example Setup (for Windows 10 1709)

1. Install and Run RWEverythingx64 1.7: This tool allows low-level access to hardware registers and memory.
2. Install and Run MSI Afterburner 4.6.1: This utility helps monitor and control graphics card settings.
3. Clone OpenDMA Repository: Clone the OpenDMA repository and open it in Visual Studio.
4. Open Target (This PC): Identify the target process whose memory you want to read.
5. Run OpenDMA: Execute the OpenDMA application and enjoy exploring the process's virtual memory!
