sup. been away from the ps3 for a while and i have a Q.
The E3 flasher has allowed successful dual booting, but requires 2 hard drives.

question i have is if while on 3.55 you install something like a CoD mod menu or Snes emulator

when switching back to 4.0 those installs will not be there bcuz you are switching Hard Drives correct?

sorry been at the x360 scene :o
