Ok so I wanted to buy a modded xbox 360 after being out of the whole mod thing for a while. Someone offered me an xbox with firmware LT 1.1. Now I thought there was only, Xtreme 1.51, 1.6 etc. So my question. Is LT 1.1 better than Xtreme 1.6? Basically Ill want to play new games like wave 4 and 5, just wondering if LT 1.1 is enough or if I should upgrade. Thanks.
