Thread: [PI]Help with adding GFX

I need to know where to put the .dat file and where to add this code

Code:

if(j == 425){ // Barrelchest
				cache[j].anInt405 = 9210;
				cache[j].anInt406 = 5871;
				cache[j].aAnimation_407 = Animation.anims[cache[j].anInt406];
			}

Please help me, i've tried for almost an hour now but still can't find where.
