Why Pay $100+ for DMA Firmware?

When your DMA firmware gets detected, sellers charge you $100-$300 for a "new" firmware. Buy DMA firmware from Captain75T instead — get a brand new identity for just $9.99.

Traditional Sellers

DMA Firmware Features

Custom DMA Firmware Generator

Professional DMA firmware generation with hardware-verified bitstream patching. Every build is unique.

🎲

Unique DMA Firmware Per Build

Every DMA firmware build has randomized serial numbers (DSN), revision, subsystem IDs, and BAR types. No two builds are ever the same.

🛡

Anti-Fingerprint DMA Firmware

Per-profile PCIe capability chains that match real hardware signatures. Full config space emulation — your DMA card looks exactly like a real device.

⚡

Instant DMA Firmware Generation

DMA firmware ready in ~10 seconds using bitstream-level patching. No Vivado, no FPGA toolchain, no waiting for sellers.

💻

6 Real Device Profiles

Intel I211, Realtek 8168, Intel AX200, I225, R8125, I350 — all with accurate VID/DID and capability chains.

📌

Both 75T & 35T

Full support for Captain75T (XC7A75T) and ACE 35T (XC7A35T) boards. Same quality, same features.

🔒

No DNA Lock

Works on any Captain75T or ACE 35T card. No DNA locking, no 1-card restriction. Use the same account for all your cards.

How To Buy DMA Firmware

How It Works

Four simple steps from signup to flashing your new DMA firmware.

1

Create Account

Sign up in seconds. Just email and password — no personal info required.

2

Buy DMA Firmware Credit

Purchase a DMA firmware build credit for $9.99 via Stripe. Or use a coupon code if you have one.

3

DMA Firmware FAQ

DMA Firmware — Frequently Asked Questions

Everything you need to know before buying DMA firmware.

How is this different from buying firmware from a seller?
Sellers charge $100-$300 for firmware that's often shared with other customers and locked to your specific card via DNA. With Captain75T, you generate your own unique firmware instantly for $9.99. Every build has completely randomized identifiers — serial numbers, capability chains, revision IDs — making each firmware truly one-of-a-kind. And it works on any compatible card, no DNA lock.
What happens when my firmware gets detected or banned?
Just generate a new one! That's the whole point. Instead of paying another $100+ to your firmware seller and waiting days, you spend $9.99 and have a brand new firmware with a completely different identity in about 10 seconds. New serial numbers, new device fingerprint, new capability chains — it looks like an entirely different device to the system.
Is each build truly unique?
Yes. Every single build gets randomized Device Serial Numbers (DSN), revision IDs, subsystem IDs, and BAR type configurations. The PCIe capability chains match real hardware signatures for your chosen device profile. No two firmware builds will ever have the same identity — we patch at the FPGA bitstream level using prjxray, modifying hundreds of bits per build.
What boards are supported?
We support the Captain75T (Xilinx XC7A75T) and ACE 35T (Xilinx XC7A35T) DMA boards. Both use the Artix-7 FPGA family and are fully compatible with our bitstream patching engine. Select your board type when generating firmware.
Will this work on any 75T or 35T card?
Yes. Unlike seller firmware that's often DNA-locked to a single specific card, our firmware works on any Captain75T or ACE 35T card. No restrictions, no card-specific locks. You can use the same account and generate firmware for multiple cards.
How do I flash the firmware?
Download the .bin file from your dashboard after generating. Flash it to your DMA card via JTAG using a CH347 programmer. The process writes to the SPI flash at address 0x00000000. The same flashing process you use with any other firmware.
What device profiles are available?
We offer 6 pre-configured profiles: Intel I211 (GbE), Realtek RTL8168 (GbE), Intel Wi-Fi 6 AX200, Intel I225-V (2.5G), Realtek RTL8125 (2.5G), and Intel I350 (GbE). Each profile includes accurate PCIe capability chains matching real hardware. You can also enter custom VID/DID values.
Do I need Vivado or any FPGA tools?
No. Our system uses prjxray bitstream-level patching to modify FPGA firmware directly at the frame level. No Vivado, no FPGA toolchain, no compilation needed on your end. Everything is handled server-side — you just click Generate and download the .bin file.
