This game's medals are easy enough to obtain without hacking. I think it'd be more of a waste of time to figure out how to hack than just simply playing it.

I tried finding the shots number because that's the only annoying medal to get in my opinion, but changing it didn't make it trigger earlier. I actually had to shoot 200 times to get that medal.

There's already a pretty full walkthrough here http://www.gretelandhansel.com/walkthrough.html also that tells you how to get everything.

I only tend to look at a game if I can't manage to get the medal legit. In this case - there's a walkthrough, nuff said.

In terms of the 200 shots, having had a quick look at the code (badly mangled together), it uses flash frames to keep the count of shots made, so there's no easy of changing this, the quickest way is to sit there and fire the slingshot 200 times, dull as it is. I suggest finding a good book!

Speedhack makes you shoot slightly quicker.
