Hidden PCIe DMA Firmware FPGA

I need custom firmware for a PCIe-based DMA card so a second PC can attach to my Windows gaming rig, read or alter memory, and feed data back—yet look to both Windows and Fortnite’s anti-cheat as nothing more suspicious than a standard IDE ATA/ATAPI controller.

The core goals are:
• Mask all DMA activity and device signatures so common anti-cheat sweeps find only an ordinary storage controller.
• Keep full, low-latency read / write access to physical memory from the host PC.
• Allow on-the-fly interception or modification of data in transit when required.

You’re free to start from an existing open-source project (e.g., PCILeech-compatible hardware) or write bare-metal code, as long as the finished image flashes cleanly to the card and survives stress testing under current Fortnite builds.

Deliverables:
1. Compiled firmware image and flashing procedure.
2. Source code with build instructions.
3. A brief validation guide showing the card enumerating in Windows as the spoofed controller, passing anti-cheat checks, and succeeding in remote memory reads/writes.

If you’ve already tackled stealth DMA or similar PCIe camouflage, your experience will be invaluable. Let’s discuss chipsets you prefer to target and the test environment you’ll need access to.
