so ... i have found a problem in tha samsung firmware (XTREM) so to all hacker can you fix this !!
i own 2 XBOX 360 : Hitachi and Samsung ! i have flashed my two consoles and i noticed that the samsung is spend VERY MUCH time in loading inside a game (the same game tried on the 2 Consoles !!!!!!)
BUT i picked up my PGR 3 (original one)
and with a chronometer
i found that the loading times are identical !!!!!!!!!
so in conclusion the SAMSUG firmware have a little problem and i hope it will be fixed and all people can enjoy !!!
