@Coro @bguerville
so i formatted the HDD and installed the evilnat cfw 4.87 successfully
i cant thank u guys enough for this
i do have some follow up questions tho
Situation - I dont want anything to do with PSN but i want to be able to FTP with pc
1. If there is no PSN account logged in the console, is there a risk if i keep the ps3 connected to internet ?
2. If there is a risk, how to do i completely disable the console to communicate with PSN servers, altho having the FTP feature active
3. I have installed multiman, there are 3 kinds of game format in my possession (folders, .pkg and .iso). Is there a nice guide which can teach me how to get all the 3 kinds of game format run on the ps3 ?
4. What is the preferred game format to install according to you guys?
5. Do i need to make changes to get the ps2 and psx games run or it is available as a feature under cfw?
Your questions cover a wide range of topics actually & for each of them, you will find different people knowledgeable in the specifics to answer your questions.
Here I will only answer in broad terms.
1. No risk at all in using Internet without PSN connection.
The PSN connection is not a requirement to an Internet connection, or to be more precise, PSN requires Internet but Internet does not require PSN.
However remember that for a number of things you will need PSN, unless you stick to gaming on retail game discs backups.
For instance, for a number of features, console activation is required and if the console is not yet activated, you will have to connect it to PSN to activate it.
It's obviously safer to activate while still on OFW 4.87 but it can be done from CFW 4.87 without too much risk too, it will be up to you from now on to decide whether you prefer to be extra safe ie reinstall OFW, do the activation then rejailbreak or not & take a minimal risk, do it all on CFW using mitigations like PSNPatch & possibly idps spoofing.
2. Make sure that you disable the auto login setting for any user profiles in which a PSN account is registered.
3 & 4. There are 3 main types of game backups.
A) JB folder games. It is a simple copy of the folders & files found on a PS3 Game BD Disc, it is a legacy format which nowadays is mostly used for game modding or other specific situations.
B) PKG games. Those are PSN game releases, for each of those games you install, you must also install an appropriate PSN license.
C) ISO games. Those are ISO images of PS3 Games BD Discs. ISO is the recommended game backup format to use on CFW.
If you have a retail disc based game library to backup, the most common way to go is to create ps3 compatible iso images (use the makeps3iso utility either on PC or through Irisman on ps3) & store them on a ntfs formatted external USB hdd to be mounted via a backup manager.
Note that it's recommended to avoid storing iso or legacy JB folder backups on the internal hdd itself because when you mount a game stored on the internal hdd, the hdd must play the role of the BD disc & still do its regular job. It means extra strain on the hdd & a performance hit that largely depends on the game itself, some games use the BD extensively, others not so much.
5. Ps2 support level depends on the console model. On early phat models, there is hardware assisting the emulation. For all other models, you have to rely on a modded ps2emu (one of Sony's ps2 emulators for ps3), the emu files are included with Cobra/Mamba on CFWs.
On software emulation, compatibility & perf are not as good as on hardware assisted emu as you may already have guessed.
Ps2 DVD retail games can be mounted as iso (or cue/bin for game CDs) files or they can be in ps2 classics format etc..
There is a compatibility list to find out whether a specific game can be played with the emulator, don't expect miracles though. In recent years, config files to improve compatibility & perf of certain games have been put together, ongoing projects like Managunz or webMAN-MOD integrate those files bit by bit, one file per game id at a time, but with older managers like multiman, you will need to fiddle manually if you wanna use them.
Regarding ps1 games, those can also be used through backup managers like multiman. Compatibility is good, most ps1 titles can be played on ps3.
