Well im not sure if this will help anyone but it works 100% of the time for me so thank me if it does. For every other map in the game theres 2 address's associated with loading the map and 2 associated with describing the map (so i have assumed from research) so why not for crespo dg. There are 8 address's correct? 2 for A to describe A, 2 for B to describe B, and 2 for C to describe C, and the remaining two are obviously associated with loading the 3 maps. I found that if you change all 6 bottom address's it will engage wall hack for A, B and C as the last 6 are the 6 associated in describing A, B and C runs. Changing the first two will always cause crashes as it is associated in loading all 3 runs. This is also true of all other maps, the top two will always be associated with loading the map. So if you get 4, its the bottom two. If you get 6, it's the bottom 4 and so on and so on. And this is much more clear then Noble's post, and some people are visual learners, have to take how people learn into factor when considering who's tut is better, so honestly both of your posts probably helped a lot of people good job guys.
