Direct Memory Access
DMA cheats, firmware and hardware.
DMA means Direct Memory Access. In a two-PC gaming setup, a PCIe DMA card lets software on a second computer read memory from the gaming PC. Compare game-specific DMA software, custom firmware and configured hardware here, then use the guides to build a compatible stack.
Choose the layer
Start with what your setup is missing.
DMA is a stack, not one download. You need compatible hardware, firmware and software. Buy only the missing layer, or use the configurator when you want the parts selected together.
01
Game-specific DMA
Choose software by game when you already own a compatible card, firmware and second-PC setup.
Compare games 02Custom DMA firmware
Order firmware for a supported 75T, 100T, M.2 or ZDMA board after confirming your exact hardware.
View firmware 03Complete DMA hardware
Configure the card, firmware, software and optional display or input hardware as one checked build.
Build a kitDMA setup checklist
What a DMA setup actually needs.
Exact requirements vary by card and game, but this is the usual two-PC architecture. Confirm every connection before you buy or flash anything.
Read the second-PC setup guideDMA card
A compatible FPGA board sits in a free PCIe slot on the gaming PC and provides the hardware path for memory access.
Second PC
The second Windows machine controls the card, runs the DMA software and handles radar or overlay output.
Custom firmware
Firmware configures how the FPGA board behaves. It must match the card and the intended environment; it is not a universal file.
USB 3.0 link
A direct, stable USB connection joins the DMA card to the second PC. Motherboard ports are preferred over hubs.
Input device, when needed
KMBox, MAKCU, Teensy and similar devices can route input for supported features. The exact device depends on the software.
Compatible software
The game-specific build, card, firmware and input method have to form one compatible stack. Check live status before buying.
Compare the architecture
DMA vs external software cheats.
Both are external to the game code in different ways. DMA moves the memory-reading path to hardware and a second PC; a conventional external cheat still runs locally on the gaming PC. Neither architecture removes detection risk.
| Factor | DMA setup | External software |
|---|---|---|
| Where processing runs | Primarily on a second computer | On the gaming PC |
| Extra hardware | DMA card and usually a second PC | Usually none |
| Gaming-PC footprint | No injected module is required for a read-only setup | A local process, driver or injected component may be used |
| Setup difficulty | Higher: card, firmware, cables and display/input path | Lower: install, configure and launch |
| Best fit | Players who already understand a two-PC hardware stack | Players who want the simplest software-only route |
| Detection risk | Depends on the complete hardware and software stack | Depends on the loader, driver, hooks and behaviour |

Open a product to compare providers, licence periods, features and hardware requirements. Check the live status page before ordering because compatibility can change after game and anti-cheat updates.
From card to working stack
A practical DMA setup order.
Compatibility decisions come first. Flashing a random file or buying the software before checking the card usually creates avoidable support work.
- 1
Confirm the gaming PC
Check for a free PCIe slot, supported Windows version and a direct route for the DMA card.
- 2
Identify the DMA card
Record the exact FPGA board and hardware identifiers before choosing or flashing firmware.
- 3
Prepare the second PC
Install prerequisites and drivers, connect USB 3.0 directly and test the card before adding game software.
- 4
Choose firmware and software
Match the board, target game and required input or display device as one compatible stack.
- 5
Verify live status
Review the product status and setup documentation after every major game or anti-cheat update.
Clear answers first
DMA FAQ.
What does DMA mean?+
DMA means Direct Memory Access. In a gaming setup, a PCIe DMA card in the gaming PC can expose memory to software running on a separate computer. That second computer processes the data instead of running the cheat inside the game process.
What hardware does a DMA setup need?+
A typical setup needs a compatible PCIe DMA card, a free PCIe slot in the gaming PC, a second Windows computer, a direct USB 3.0 connection, compatible firmware and game-specific software. A KMBox, MAKCU, Teensy or fuser may be added when the chosen features require input or display routing.
Do DMA cheats require a second PC?+
Most PC gaming DMA setups use a second computer to control the card, read memory and run the DMA software. The second machine can often be modest, but its exact requirements depend on the software and display method.
Is a fuser required for DMA?+
Not always. A fuser combines display sources so an overlay can be viewed on one screen. Radar-only, network-overlay and some capture-card setups can use a different display path. Check the requirements of the specific product before ordering.
Is DMA firmware universal?+
No. Firmware compatibility depends on the FPGA board, hardware identifiers, target environment and selected tier. Confirm the exact card model before flashing or purchasing custom firmware.
Which games have DMA products?+
The current Lethal Solutions catalogue includes game-specific DMA options for Fortnite, Valorant, Rust, Apex Legends, Call of Duty, Arc Raiders, GTA V and FiveM. Availability can change after game and anti-cheat updates, so check the live status page before ordering.
Are DMA cheats undetectable?+
No setup should be described as impossible to detect. DMA can reduce the software footprint on the gaming PC, but risk still depends on firmware, device behaviour, input method, software, configuration and player behaviour.
Compatibility changes. Use the live status page and confirm your exact DMA card with support before placing a firmware or hardware order.
