Robin Hoods Playground

so i can see if the firmware is 1.51 by trying to play a new release i suppose. i will try raiden fighter aces , question though , will my system get jacked if i try to play a new release and the firmware is older then 1.51 will it?

i bought a 360 with 3 flashing lights, i sent it to micro$oft and they returned it working for free, although i confirmed most likely only added a heat sink rather then fixing the x-clamp(like i fixed my other 360`s x-clamp) , i wonder how long the heat sink fix will last, anywayz i`ve had another 3...
