look what they are, thats all i can really say. cause most of the tuts that have been released are based on luck basically they don't say why changing certain ones will make you crash etc. so you will always have to try it and won't be able to go everytime to the exact one you need to change.
two of the results will be where the .mac loads from so it'll be displayed like (don't actually remember where they load from so this just an example) 'blah/blah/blah/Python.mac' editing either the two that look like this will make you crash. then the other result will look like
'Python.mac,Map\19_Python\NPC_19_Python.csv,2,18,1 .7,-70,80,12,50,50,' just like how it looks when your editing your data pak file editing this won't have any effect whatsoever. then the last one will be just .mac and around it, it will either have 100-330-1313-11-1131 random numbers connected by hyphens or it will have just random characters around it, this is the one you wanna edit. you can only look at it this why in the hex section in memory viewer, so unless you look at whats around it you'll never workout what one you can edit everytime.
anyways kiki's tut is probably the best at showing which one is the correct one to edit, cause how i explained it you probably get a lil confused xd
