[bomberman] edit/create levels?

hi

so, i guess some know and already have bomberman touch. really cool game on the iphone.
well, all that intro text wasnt my idea of a straight gameplay, so i checked the .app and found the strings, edited it out and now it loads quicker (since i dont have to watch that text again).

so, i found the files "stage00.sp" (which is the level file for the first lever just after the plane crash).
i somehow managed to add a few other vilains, and "grow some grass", but wasnt able to modify the level the way i wanted to.

i also did not found that much of a common syntax compared to the other level files.

has anybody already had success in modifying the levelfiles for that game' :)
