I find it rather ironic and completely hypocritical that hackers complain/worry about people hacking their work. Not to mention that is the completely opposite of what the hacking community
should be standing for. IE: the sharing and free distribution of games/information. I can't help but wonder what is going through people's minds when they take information found by others, tools built by others, and use them to modify a game made by others -- then turn around and pass it out with fears of it being subjected to the same treatment.
ROM hacking has come as far as it has only because people have been willing to share and contribute their work towards others' goals. If you can't share that concept --- if you can only take and not give --- you're not going to get any of my sympathy =P
My only concern with anti-hacking tools is just to make sure people can't open it up in an editor and look at everything (ie spoilers).
That was actually my concern when I implimented the ghetto "protection" feature in Hackster (hence the message you get when you try to open a "protected" ROM). As has been mentioned it's easily bypassable.
Though my concern for that now isn't near what it was in the past. If people have more fun cheating -- let 'em cheat! If I could go back in time I'd probably remove that protection thing.
If you really are concerned about your hack being 'claimed' by some lazy twit ...
I actually hear about this concern a lot. In fact I remember getting into a debate with someone on acmlm's who considered this a serious problem. But really.... how often does this happen? Has it ever happened? I can't recall a single time, myself. And even if it were to happen, ROM hacking circles would flood with gossip and the "thief" would probably be alienated as a result.
I just don't see this as a reasonable concern. Odds are better that you'll get hit by a bus than someone will steal your hack.
