remember one thing..if you do this manually and not with svr editor of nikethebike ,if your new pac is big than original bpe ,game will crash..you need to mod the ARC file . only other way is trying to use small textures 'til you have a pac not bigger of bpe,then add 00 bites with hex editor for having same size of bpe.try to use small textures for boots or other not really important parts
