4 byte * 1 for the lives. Will take you 3/4 searches to find it, lots of numbers. So just lose one life in each of the first four levels until you find the value, freeze it at anything higher than 2 and you should be good to get all the medals. Probably take you 3 playthroughs:
One to play until level 12 and die, one to play to 12 and win, and maybe one to get 300k/400K points, unless you manage to get that on your second playthrough.
