HelpHow to activate 255 round

Hi i was wondering how to activate 255 round. I'm using Genesys multi hack v1.0
When i check the 255 round, i create a sd room. But there's no 255 round or there's a key to activate for 255 round? . Can anyone help?

Open your Blackshot Bypass in blackshot then creat a SD,Flag or TDM room,use ce change value to "byte",then first scan the round or point,must change the round/point 3 times,and scan the round/point 3 times,Then change the value to 255!!
