Hacking Assistance If Possible... (Help with learning how to make codes)

[CreamedCheese21]

Hello. I don't know if this is the right place to ask this but... I wanted to learn how to make my own AR Codes for a long time without any devices or some kind of convoluted and risking my computer of sorts and I came across a Youtuber named CosmoCourtney who gave a rather informative video on how to do such a thing with Dolphin's Cheat Code Manager. I wanted to try to make some myself but I've been told that it A. Varies on numerous factors, B. Requires you to be specific as much as possible and have some basic knowledge of binary, decimal, hexadecimal I believe... and C. Know where to find what you looking for said Address/Value. Unfortunately, I have no base to start from so I winged it and managed to have found HP Bars (Note I'm referring towards Digimon Rumble Arena 2 that has no numbers to depict their health and such and randomly thrown in a Value and managed to find it on a whim) and was following the directions on how to make sure the constant change in an address be set in stone into a real Action Replay Code by dumping two Addresses that worked before dumping them, renaming them to "1.bin & 2.bin" files inside of a program used to create a code known as "GCNPCC". Now I've followed everything down to the last step but when I try to execute the program and put in a Value for the code (I input a value based on the values given for the HP Bars when looking through the Manager) It claims that "1.bin is not found." so I'm just at a complete standstill. I don't know if anyone still does this but if anyone knows what I'm doing wrong can you please help me? (This was the video recommended to a very nice person on Gamefaqs which I was able to make progress. I just don't know why it doesn't want to follow suit with the two renamed bin files...) Thanks for taking the time to read this at all. I just wanted to have some fun with some old games since it was the only system I've played for a long time.
