I'm gonna have to stop you there. ROM hacking is not the process of editing a ROM. That's game modification, at best. ROM hacking is the process of researching a game and figuring out how it works and where things are stored. The person who discovers the location and format of level data is a ROM hacker; the person who uses a tool or hex editor to edit level data is not. You can't call what you do ROM hacking because, frankly, it isn't even close.
