To personalize the text in n-gage copy the file 'ngiplay0x20003B78.r01'
from C\resource\apps to your memory card, then modify the hex code using x-plore on the file in C\resource\apps
then you have the original on your memory card still incase you want to change more later, or to replace the one on C\drive if you make any spelling mistakes!
the file is big so expect a wait to scroll down to the bottom half where the good stuff is
