Well, NeoGAF user 'Durante' decided to take a look at this game and after 23 minutes, the modder figured out a way to unlock the game's internal resolution."
GG Moders & Durante in this particular case :)
However, if you played Demon's Souls a lot you will immediately notice the blatant similarities between the two games. The reason From Software was able to get away with this is because of a deal they made with Sony to keep the Dark Souls title exclusive to Sony PS3 in Japan. Not really a big deal considering how the 360 sells in Japan.
As far your feelings that Demon's Souls is better than Dark Souls, well that is just your opinion. I played Demon's Souls around 600 to 700 hours and I still prefer Dark Souls. What I dislike about Dark Souls is all the nonsense that happens in PvP. I preferred Demon's Souls PvP because I felt like you could get more honorable matches, but the truth is that there was just as much bs in Demon's Souls too. However, I wish to the gaming gods that I still had my Claymore moveset from Demon's Souls in Dark Souls.
