Like a Let's Play for hacking. I'd do that if I could, could be quite informative.
Leaving aside my dislike of most let's plays I have ever seen I would have to say I don't see it.
I watch a video on a repair, device disassembly, construction of something or machining process and I might see a hand movement or something the person doing it might have done intuitively which in turn helps me. I imagine the OP is seeking that sort of thing which is fine.
It can be done for certain other types of hacking, say how to run nmap for a port scan of a server you are attacking/pen testing/making sure you have secured, or basic doxxing, or if you are in somewhere with a proper database then that, how to run a brute force/dictionary password scanner and such like. ROM hacking, at least the way I do it and can see it being done, are far more active with far more considerations that get made and I am back to failed attempts, slowdowns and branches. If you do have a more automated way that yields results on random games please do share with the class.
In another thread I said ROM hacking videos would be the inverse of machining videos as far as setup and the final results go, however I recently watched a CAD tutorial (3d design for engineering parts if you are not familiar with the term) for someone designing something from the proverbial napkin drawing of someone else ( https://www.youtube.com/watch?v=LrPggPn5BB0
and the video before it if you were curious). The dead ends, the iteration, the refinements, the jumping around (though lessened thanks to the master file and sub assembly process) all felt familiar as a ROM hacker, and were I not otherwise versed in CAD I can see things being skipped/skimmed over and causing confusion for those less versed and looking to improve.
