Hola, segun veo la diferencia entre los firmware 4.2a y 4.2b es esto:
FOr Xtreme 4.1A default backup Read Speed is same as original game disks 12x. When Original Game disk is booted, all subsequent backup loading will be at Quiet/Slow Read mode, Original Game disks are unaffected. Turn console off/on to reset back to Default backup read speed (12x). Quiet/Slow Read Speed is for quiet operation and/or cheap DVD+R DL media.
FOr Xtreme 4.1B default backup Read Speed is Quiet/Slow 2-4x. When Original Game disk is booted, all subsequent backup loading will be at Fast Read mode 12x, Original Game disks are unaffected. Turn console off/on to reset back to Default backup read speed for backups (2-4x).
Pero me podeis traducir esto al cristiano? Mi ingles esmuy malo. Gracias
