What Is DMA? Guide to Cards, Fusers and Firmware

Wondering “what is a DMA device?” or “what's the difference between the card, the fuser and the firmware?” This guide explains every part of a DMA setup in simple terms, so you know exactly what you need before you order.

What is a DMA card?

A DMA (Direct Memory Access) card is the core part of the setup — it connects through a PCIe slot and works with a second PC (a full computer or a mini PC) to read data directly. Our most popular cards are Captain DMA 75T and the 100T-class cards for pros.

What does a fuser do?

A fuser combines two displays (your main gaming display and the second PC's display) into one output, so you can run two PCs without needing two separate monitors on your desk. Models differ by supported resolution and refresh rate (4K120, 2K240, 1080P360 and more) — see all fusers.

What's the difference between the card and the firmware?

The card is the physical part (the hardware), and the firmware is the software that runs it and sets its compatibility with each game. DMA Saudi firmware comes in two options: built for one game (like Valorant firmware or COD firmware), or all-in-one for every game on a monthly subscription that keeps up with EAC and BE updates.

Is the firmware compatible with protection systems like EAC and BattlEye?

Yes — each of our firmware listings clearly states the games and protection systems it supports in the product description (such as EAC and BE), and it's updated regularly to keep up with game updates.

What is a MITM device?

A MITM device (like Heino) runs the second PC with a changing identity and encryption for better stealth and stability, and usually comes without built-in firmware — meaning you choose the right firmware for you separately. See all MITM devices.

What exactly do I need to get started?

The simplest way: order a ready-to-play bundle that combines the card, fuser and firmware in one package (starting at SAR 949), instead of buying each part separately. See all bundles sorted by price, or try the bundle picker and answer a few simple questions so we can recommend the right setup for your game and budget.

What if I already have a card and just want firmware?

You can order firmware for the game you need on its own, without a full bundle — see all firmware options available by game.
