So I was a bit curious and decided to try and hack Pokemon Red Version for the Nintendo Gameboy. I just wanted to do a little bit of reverse engineering on the ROM in order to figure out how hard it would be to replace a bit of code to change some text. Spoilers, it is a bit harder than just replacing some bytes in the ROM. You also need to open up the ROM to modify the check sum. Normally the Game Boy doesn't really care about the check sum, but I feel it is good practice to make sure all our Charizards are in a row. We will be using. This kind of video is a new style, so please let me know what you think. It is basically just doing some programming, computer science, reverse engineering, hacking, etc. and not planning it out. This is so that you can see all the mistakes and the way I approach a problem (even if it isn't the best solution).
