Assembly Programming

Perhaps it's time I focus on a game that's not BOF per se, but what I do want to start with is the very basic/rudimentary concepts of ROM hacking. More importantly, seeing as how I feel more comfortably with how hex and binary work, actually editing the bytes in a hex editor (like text in FFVI). I'm realizing (albeit the hard and painful way) that I need to start with another game, like FFVI, such as editing the item names, spell names, etc. But the issue with that is I need to know which bytes correspond to which letters, on top of that, I'll likely need to use the ROM that doesn't have a header. Before doing that, however, I need to understand how to match what bytes mean what, so I would guess the best way to learn is to first, read as many documents about hex and binary as you can, then get something Hex Workshop or WindHex32 and just go to various offsets and mess with the bytes until you start seeing results. *Sigh* Guess I'd better start from square one instead of pissing you guys off by my asininity.... I just...need to know where I need to start, what I need to use and so on.....sorry
