DMA Firmware
Works only with a DMA cardStock firmware gives the card away at once: the anti-cheat reads the PCIe device identifiers and sees a capture board. Emulated firmware replaces them so the card looks like ordinary hardware. Different anti-cheats need different firmware — each page states which ones it covers.
About firmware
Stock firmware honestly tells the system this is a developer board with direct memory access. The anti-cheat only has to read those identifiers to know everything. Emulated firmware passes the card off as an ordinary device.
No. Anti-cheats look at different traits, so firmware is built for specific families: EAC and BattlEye are one, ACE and VGK another. Each page lists what its version covers.
Check the compatibility block on the firmware page — the board models are listed there. If yours is not on the list, message us on Telegram before buying: some firmware is built for a specific revision.
Yes, whenever an anti-cheat starts checking new traits. The update comes with the same purchase — you do not buy the board again.
