Well, the author of this hack is working on another one, that's even bigger (and two games in one, heh).
I wouldn't go so far as to call it 'amatuer' -- there are many, many worse hacks out there, and this one required a lot of skill to hack (programming in 6052 assembly isn't easy).
I always considered this to be one of the best hacks out there, second only to Demo World TLC, and it's plenty hard (which would make it somewhat interesting, to see a challenging game beaten in no time), but some things are quite chaotic in design.
Overall, I still think this would be an interesting movie, and if it's not, the hack he's been working on now definitely will be when it's released.
Edit: I found the page dealing with the hack I speak of --
http://board.acmlm.org/thread.php?id=16478 -- it's pretty nice, but the screenshots have been deleted; he's uploading more soon.
