This brings up interesting conceptual problems as to what it means to beat a game. First off, I feel that entering the code to show the credits is just wasting time; entering a cheat code can't contribute to beating a game, so either the game is beaten without the code, or it isn't beaten even with the code. So the question boils down to "does setting a 'the game is beaten' flag count as beating the game?". I suspect that entering a postgame area with a glitch wouldn't count as beating the game, but I'm not sure this is the same (and we've treated the fact that the game enters a postgame state as evidence that the game is beaten before now). I'm currently leaning towards considering this invalid, but I'm certainly willing to have my mind changed, as I'm far from certain.
Are the credits possible to trigger via the code regardless of game progress, or is achieving a "game beaten" state a requirement to view the credits? If it's the former than I have serious doubts about this being a legitimate completion; the latter I question the same for different reasons. If triggering the credits happens at any time then what exactly *proves* the game state given is a legitimate "game beaten" state? I don't know the game, so I don't know the answer. Alternatively, if using the code only works after achieving a "game beaten" state, is this a *legitimate* game beaten state, or merely one that is able to show the credits? Yes, there is a difference, as has been proven in the past with Pokemon runs on the site. TL;DR I have issues with the "ending" and there's not enough detail in the submission text to answer my questions.
