Cheats are usually embedded in the memory of the game process. For example, for GTA: San Andreas, this is a substitution of the .dll file d3d9.dll, after which the code or game variables in RAM are modified through this DLL. Anti-cheats are possible and are aimed at finding modifications to the game code - for example, constantly checking checksums for code sections. Cheats, respectively, can deceive this business. A very large and confusing topic.
