can u let me know of some good vendors for firmware and boardsQuote:
The information about DMA detection are spread around various parts of different forums including UC.
1-PC cheats can get detected anytime. BE recently detected ABS. Perhaps, they might add proper hypervisor detection tomorrow and stop hypervisor based cheats. But this won't be the case with DMA. At least for the foreseeable future.
When you use a 1-PC cheat, you are risking your lovely account. My friends are on DMA since 2016-17 on BE/EAC games and they aren't banned. Some of them are never banned on VGK/FaceIT.
