Need black ops 2 sprx code for changing rank and prestige and classes

[yesitsmekid]

I have just started my first sprx menu with the help of the Paradise source code that I am using and have modified and completely changed it to my own liking and looks completely different from original. First day making sprx and consider myself quite a fast learner and it isn't very hard to actually do as I scroll through source code.

I need help or code to change stats like level and prestige in pre game lobby.
I am also hoping to find a way to change class names and add "flashing name" option but can't seem to find code anywhere.

Paradise came with this originally for stats:

case MENUS::Host:
addOption("Rank 55");
addOption("Prestige 15");
addOption("Rank 0");
addOption("Prestige 0");
switch(getOption()) {
case 0:
setClientRank(*(int*)(cg_t(0)),55);
break;
case 1:
setClientPrestige(*(int*)(cg_t(0)),15);
break;
case 2:
setClientRank(*(int*)(cg_t(0)),0);
break;
case 3:
setClientPrestige(*(int*)(cg_t(0)),0);
break;


I converted it the code to work with the pre game lobby menu and it just freezes my game and ps3 when I use it.

Any help would be appreciated. Thanks
