The DMA (Dynamic Memory Allocation) support in Cheat Engine is an example for that. API hooking works completely differently: A preloader loads a library into the game process while starting it. The library spies on dynamic memory allocations and discovery starts with recording them all.
DMA can also be used for "memory to memory" copying or moving of data within memory. DMA can offload expensive memory operations, such as large copies or scatter-gather operations, from the CPU to a dedicated DMA engine. An implementation example is the I/O Acceleration Technology.
"Cheat Tables" is a file format used by Cheat Engine to store data such as cheat addresses, scripts including Lua scripts and code locations, usually carrying the file extension.ct. Using a Cheat Table is straightforward and involves simply opening the Cheat Table through Cheat Engine and enabling/ticking the cheats stored within it.
An attacker could, for example, use a social engineering attack and send a "lucky winner" a rogue Thunderbolt device. Upon connecting to a computer, the device, through its direct and unimpeded access to the physical address space, would be able to bypass almost all security measures of the OS and have the ability to read encryption keys, install malware, or control other system devices.
The first game using Source 2, Dota 2, was ported over from the original Source engine. One of The Lab's minigame Robot Repair uses Source 2 engine while rest of seven uses Unity's engine. Spring: C++: C, C++, Java/JVM, Lua, Python: Yes 3D Windows, Linux, macOS: Balanced Annihilation, Zero-K: GPL-2.0-or-later: RTS, simulated events, OpenGL ...
Cheating in video games involves a video game player using various methods to create an advantage beyond normal gameplay, usually in order to make the game easier.Cheats may be activated from within the game itself (a cheat code implemented by the original game developers), or created by third-party software (a game trainer or debugger) or hardware (a cheat cartridge).

I/O Acceleration Technology (I/OAT) is a DMA engine (an embedded DMA controller) by Intel bundled with high-end server motherboards, that offloads memory copies from the main processor by performing direct memory accesses (DMA). It is typically used for accelerating network traffic, but supports any kind of copy.
