Anyway, this Tang FPGA card is a proper dev kit for an exotic FPGA (Gowin). They have nothing to do with gaming "DMA" cheating cards. The "DMA" cards seem to feature Xylinx (AMD) FPGAs. They come in 35T, 75T, and 100T variations, each corresponding with a different Xylinx Artix FPGA with roughly the same number of LUs (35k, 75k, and 100k). I'm not sure how useful these cards would be for other uses, but I did find a 75T model for C$120 (before AliExpress coupon shenanigans). 😋 Also I think it's funny how they seem to be going for a "stealth" aesthetic. 🤣

I haven't confirmed this, but in trying to understand how these DMA game cheating FPGA cards work, I found it suggested that they pretend to be SATA storage devices or network adapters, and sneak access to the main memory that way. Anti-cheat systems seem to combat this by enforcing strict IOMMU policies (i.e. who can read/write what), and if a DMA card is found, flashing their own firmware to the card and "soft bricking" the PC it's plugged into. 😳 Dayum. 😳 So haha wow, DMA cheat firmware devs need to now security harden their hardware and software to stop anti-cheat software from bricking them. 🤣 This article claims the cheat hardware costs $6k!? Maybe the early cards did, but not so much anymore. 😋 https://www.tomshardware.com/software/valorant-dev-bans-players-who-spent-usd6-000-on-cheats-then-trolls-them-on-social-media-studio-tweets-congrats-to-the-owners-of-a-brand-new-usd6k-paperweight
