Rumors and Hopes - busted?
The following interview was conducted between maxconsole.net and a "well respected PSP developer" about the future of homebrew and firmware solutions. Note that this is the opinion of one developer and may not represent the opinions of the majority of developers in the PSP scene as a whole. Either way, it's an interesting read, if a bit disheartening.
Rumour: A downgrader has been released by WAB?
FALSE! WAB have simply released the decrypted PRX files from the 1.50 and 1.51 updates. These are just pieces of code which are responsible for performing the flash upgrade procedure and serve only for research into the file format of the PSAR file etc.
This DOES NOT let you downgrade your 1.51/1.52 and does not really get us any closer to being able to do this for the simple reason that before you can downgrade your 1.51/1.52 (without manually programming the PSP flash chip using a hardware based method) you must first be able to execute code on it, currently there is NO KNOWN way to execute code on these firmware versions.
Furthermore, what WAB has released is far from a breakthrough and not really anything new. Various people have had the upgrade PRX as well as many other encrypted PRX files (from flash, etc) decrypted for months. In fact, there is even publicly available code which will decrypt PRX files on the PS2Dev server and I wouldn't be surprised if this is what was used by WAB to get their decrypted files:
Rumor: If a method is found to downgrade my PSP I will be able to downgrade to 1.0 and both use homebrew and play all my games?
FALSE! If it ever becomes possible to downgrade to 1.0 then you will be able to use homebrew however the amount of games you will be able to use will become more limited as time goes on.
There are already games appearing which require 1.50 firmware to be installed and the number of games with a minimum firmware requirement is only going to grow. Eventually games will require something like 2.0 firmware before they will run meaning that in order to play these games you are going to need to give up the capability of running homebrew software (or hope that some sort of dual-flash system becomes possible in the future, or an exploit is found in recent firmware).
While it is possible to skip the flash version check performed by the PSP OS, this will not help you run a game if your firmware does not meet the requirement. For example, games which require at least 1.50 firmware import functions from the PSP kernel which are not found in the 1.0 firmware. If you attempt to run a 1.50 game on a 1.00 PSP then loading will fail due to these missing functions.
To summarise, downgrading your PSP firmware is not the solution we are looking for. The next batch of new releases are probably going to require your PSP to be updated to at least 1.52, and more recent firmware builds
will be getting released as needed by Sony in order to combat homebrew and/or piracy (and hopefully even add some new features.)
Sure, new exploits may be found in future firmware releases but the security is only going to get tighter and eventually its going to get to the point where an exploit will not be found within the PSP's life cycle. Upgradeable firmware really was a smart decision for Sony to make since it is a great way for them to close off any holes which can potentially lead to homebrew and/or piracy. It looks like a hardware mod may be the only viable long-term solution, or possibly a hacked firmware. The possibility of a hacked firmware appearing is VERY SLIM due to the fact that all the executable code inside the PSP firmware is encrypted and currently ONLY Sony can perform the encryption.
It is very unlikely that any 3rd parties will ever be able to perform this encryption themselves. If you cant edit or inject your own code it makes hacked firmware very hard if not impossible.
everyone against sony? Swwweeeeeeeet.
I willsign that petition with my real signature and im sure everyone I know and thier mamas will sign it too. Hell......my grandma said she'll sign. (She loves Mario Bros.) :D
