Hacking Regarding save files....

[Gamemaster1379]

I've always been one who enjoyed exploring beta locations of games, and with all the homebrew applications out, I was wondering if such a "user friendly" (noob

) one existed in which starting location on a game could be edited (Twilight Princess, for example). Or simpler yet, is there any known locations where save data files for given games can be found that start the player out in beta locations?
