(25/08/03/Sun 11:28) After listening to the lecture, I learned a lot about HW/SW. The content about H/W equipment was really good. Thank you for creating such a great lecture.

Lecture quality unsatisfactory.

Lecture quality is unsatisfactory.

It was very useful. I think that attaching and detaching general components without data and changing the flow of logic is a kind of hardware hacking. Anyway, I think it was good to learn in detail how to proceed with overall embedded hacking.

I am not satisfied with the quality of the lecture. Before taking this lecture, I studied game hacking by searching only the necessary parts on platforms like YouTube. So, I naturally wanted to fill in the missing parts and learn more about Frida, so I purchased the lecture. However, this lecture is such a waste of money and time. It is obvious that Instructor Shin Jae-won did not prepare for the lecture at all.. In the first lecture, when installing the emulator on the virtual machine, it seems that he moved to the main computer due to an error, so I thought that this part should be reviewed in advance before recording the lecture. Also, in the second lecture, the title is "Unity-based Game Hacking (Mono)", but instead of hacking by ripping off the mono game APK, he only uses Cheat Engine to hack. If that was the case, why didn't he title it "Mobile Game Hacking with Cheat Engine"? Also, in the lecture, if you search with 4 Bytes and it doesn't work, you should have said that you try with Float or other types of values or try using fuzzy search, and if it doesn't work, the value will be saved to the server. Instead, you just try with 4 Bytes and if it doesn't work, it's saved to the server. I wonder if this is right. Also, if you search with 4 Bytes, you should press Control F6 in the memory viewer to convert it to 4 Bytes and search the surrounding memory, but you only search with Hex. It seems like this lecture has many loopholes. In conclusion, the instructor didn't prepare the lecture at all, and because of that, the explanation was also inadequate. Instructor Shin Jae-won. I hope you don't do this when you film other lectures.
