Several ways of cheating or altering the game are already floating around the intertubes so I'm guessing you're looking for something a little more out of the ordinary than "number of bombs remaining" or whatnot.
What are you looking for in particular?
(Edit: For what it's worth, the player data starts at 004F77F8 (in the original full release that is - I don't know if the patch that was released lately changes around anything; haven't installed that one yet). If you want to do a bit of exploring on your own, you're likely to find a lot of useful values starting there. Ex, 004F7810 is your score, 004F7820 your graze count, 004F782C the PiV... etc..)
