I am writing this post for one reason: Clarifying the newbie confusion as to how to play and copy backup PS3 games from a HDD.
I remember the days when all one had to do was install a modchip on a console in order to play backups. However it seems that this might be a little different with the Playstation 3.
So here is what I have learnt so far (correct me if I am wrong)... Before playing PS3 games from a HDD, one has first to hack into their PS3. This hacking is what is referred to as jailbreaking. Jailbreaking can be done with USB devices that are sold around the net. e.g: PS jailbreaker, ecliPS3. There are even ways of doing it with the Ipod. All one has to do is follow the tutorial.
*Please note that playstation 3s with a OFW > 3.55 cannot be jailbroken.
After jailbreaking the ps3 one has to install a CFW, and a backup manager onto the PS3 internal HDD. In addition one must have a loader such as multiman in order to load the PS3 backups into the PS3 HDD. I have a bit of a problem here, can games only be ran from the PS3 internal HDD, or can they also be ran from an external HDD.
Basically here's my point, if all the above is true then that means that it's not necessary to open my PS3 like I did the PS2 or PS1 in order to play backup games from the HDD. This means that the Infectus2, and Progskeet are only necessary to downgrade my console. (Does that mean I can remove them after downgrading ? Sorry but I don't understand what all the NOR/NAND mean). Any help will be appreciated. Thank you.
If you have a ps3 with firmware 3.55 or below then you don't need to use any dongle to jailbreak anymore you can just install a cfw from usb stick for free. The ps3 is mostly exploited via software if below 3.55 and hardware such as progskeet are only required, like you said already, to downgrade back to 3.55. Some games work from internal, some from external, but you should use the latest version of multiman to load your backups.
