Oh, man, if you're trying to learn software disassembly then yeah, fmhy.net won't help you much; but I would also advise against going to an AI for that kind of expertise. You'll be much better off starting with this video by John Hammond, he's pretty introductory, and exploring his channel/others from there; he'll teach you more about picking apart software in ~30 minutes than you're likely to actually internalize and learn from chatting with an LLM all day (which will probably try to moralize/sanitize its outputs because CrAcKiNg GaMeS iS wRoNg). I'm not saying the AI can't be helpful once you know the right questions to ask, but you most likely don't want to go all-in on one to teach you.

Also as an aside relating to that video, Cheat Engine is effectively malware these days (Sources: 1, 2, I used to have more but they purged their forums/github issues of evidence), so I'd recommend something like PINCE instead (or just grab an old version of CE, if it'll let you install 6.3 I recall it being okay). Once you've outgrown what it can provide you, you'll likely graduate to using Ghidra, but I would advise starting simple and small to learn.
