Dann hab ich wenigstens die Sicherheit, dass ich im Bedarfsfall auch zu 1.5 downgraden kann

Bevor ich mich jetzt dumm und dusslig suche... hat die deutsche Version nun wirklich die 2.0 drauf, und welchen Vorteil hatte gleich nochmal die alte Softwareversion?!?

Leider laufen auf der alten Firmware auch Raubkopien der Spiele.

2 meiner Kumpels findens natürlich total geil Raubkopien zu zocken (der eine natürlich auch ne ganz übel gemoddete XBOX am Start). Ich muss zugeben, dass ich für mein N-Gage auch Raubkopien hatte. Allerdings waren die Games es meist nicht Wert 40 Euro dafür auszugeben und ich hab die wenigsten öfter als 2 mal gespielt.

Ich will ja nicht der Spielverderber sein, aber dazu gibt es schon einen Threat. Jegliche neuen Informationen sind darauf herzlich willkommen.

Doch kein Firmware Downgrade?
Ein scheinbar sehr PSP bewandter Programmierer stellt ind Frage, dass ein Downgrade der PSP Firmware überhaupt möglich ist. Was er genau zu sagen hat:
Talking Point: Non Existant PSP Downgrader... ?
The highly respected MaxConsole user known as 'Mr A' has let us know his thoughts on the rumoured WAB PSP downgrader and what it will take to actually make a firmware downgrader for the PSP . The editorial contains a few minor insults but most importantly 'Mr A' backs himself up with technical information as we have all come to expect from him. Let's just get straight that this is HIS view and not written by MaxConsole staff!
Recently we have all been exposed to a large amount of hype and rumors relating to attempts to downgrade PSP's firmware for the purpose of using homebrew software. Two groups in particular, WAB and PSP-DEV have been claiming that they have a downgrader working but as yet all we have seen from either of these groups are a bunch of faked videos - no actual information or anything else which might suggest that they actually do have something working.
I have quite a bit of experience with reverse engineering etc and have personally examined the PSP firmware upgrade procedure by decrypting the updater executable and accompanying data file so I know how it all works. If either WAB or PSP-DEV had the skills to do this then they would probably never have claimed that they could downgrade the firmware since they would know exactly what is involved and that its not possible through software alone. I will try to explain how this all works without getting too technical..
As you know, the PSP upgrades come in the form of EBOOT.PBP archive files. The archives contain the encrypted upgrade executable (DATA.PSP), the encrypted data file (DATA.PSAR) and some other information such as the firmware version which is contained in the PARAM.SFO file. The PARAM.SFO file has been the focus of many downgrade attempts, but all these attempts have been in vain. While the PSP OS does indeed use this file to get the firmware version which will be upgraded to, even if you can bypass this first check and actually get a updater running (say 1.50 updater on 1.52 system) you will still not be able to downgrade.
Maybe you agree with the article, maybe you don't - either way we want to hear from you in the forum thread link below!
This is because there is yet another check inside the update executable. The version information for the firmware which will be updated to is stored alongwith the rest of the upgrade data in the DATA.PSAR file. Once you start the upgrade the version information from the DATA.PSAR file is compared with the version of the firmware your PSP is currently running. If your PSP is running a more recent version than is contained in the DATA.PSAR file then you will receive an error.
Currently it is not possible for us to encrypt our own DATA.PSAR files or executable files. So we cannot simply edit the version information in the PSAR and we cannot simply patch out the check in the updater executable. I bet now some of you are thinking why dont you just change the firmware on your PSP so its reported as 1.00, then the upgrade will work!. In order to change the firmware version you will need to be able to execute unsigned code, if this was possible then a downgrade might not even be needed at all.
I dont see a working downgrade method appearing any time soon, especially with everybody going about it the wrong way! WAB dont seem to know what they are doing and they probably think that since you guys dont know either they can feed you crap. I just hope after reading this you are a bit more educated on the subject and now the lies they feed wont stick or continue giving people false hope for something which will most probably never come (at least not from these kids ala WAB).
And for those of you who have never heard of Mr A before, he was the first developer to correctly identify the changes of the v2.0 firmware and why it will be HARD to crack. Even IGN picked up on what he said, time will tell if he is right on this one too!
Oh and we hate having to say this time and time again, but unfortunately other websites forget basic ethics, so...if you wish to use any part of this article or refer to it then we expect MaxConsole to be clearly creditied.

News aus dem PSP Magazin :
"Schon vor einigen Tagen entdeckte ein gewisser "toc2rta" die Möglichkeit selbstgeschriebenden Programmcode auf einer PSP mit 2.0 Firmware auszuführen. Hierfür verwendete er einen Exploit im Bildbetrachtungsprogramm: Wählt man auf der PSP eine manipulierte Datei als Hintergrundbild aus, so führt die PSP den darin eingeschleusten Code aus.
Nach dem obligatorischen ersten "Hello World" Programm, einiger Grafikdemo und eine Pong Variante für die 2.0, war es nur eine Frage der Zeit bis die Cracker auch größere "Erfolge" verbuchen konnten. So ist es jetzt scheinbar gelungen eine PSP Firmware Version 2.0 auf die ältere Programmversion 1.50 "downzugraden". Diese ist in der Szene beliebt, da sich darauf ohne großen Aufwand die sogenannte "Homebrew" (selbstgeschriebene Software) ausführen lässt."
Bitte keine Links oder sonstwas in der Art posten, aber das is ja klar, ne..Muss jeder für sich selbst entscheiden, was er mit seiner PSP anstellt und wie er da ran kommt...die Homebrew- und Emu-Szene wirds jedoch freuen ;-)

Ich hab auch was davon gehört:
Mom festhalten:
ACHTUNG!!! Gestern wurde im Netz eine Idee zum Downgraden der PSP bekanntgegeben: UMD mit Firmware 2.0 starten, bei Meldung dass man Strom dran und Batterie voll haben soll, gegen ein Spiel mit 1.50 Upgrade wechseln und dann flashen. Wir können bestätigen, dass dieser Trick NICHT (!) funktioniert und man seine PSP innerhalb kürzester Zeit in ein wertloses schwarzes Stück Elektronik ohne Funktion verwandelt. Fazit: Finger Weg ;-)
so und nun folgendes:
jo das ding scheint wohl zu funktionieren.
NFO:
-> This is has not been tested, it could brick your PSP <-
-> I AM NOT RESPONSABLE FOR EVENTUALS DAMAGES <-
Downgrading 2.00 -> 1.50 method
-------------------------------
Requires :
----------
- PSP 2.00 (if you have an 1.51 or 1.52, update to 2.00)
- The 1.50 EBOOT.PBP update (included in package)
- MPHDowngrader (included in package)
Installation :
--------------
- Create a UPDATE folder in PSP/GAME/ folder of your memory stick
- Copy EBOOT.PBP (update 1.50) in UPDATE folder
- Unpack MPHDowngrader.zip
- Copy overflow.tif in your PSP/PHOTO/ folder of your memory stick
- Copy h.bin in root of your memory stick
- Copy index.dat in root of your memory stick
- Plug the AC adaptor
Then, enter in VSHELL PHOTO MENU, this will launch Version Changer.
Create an USB connection and if the Version Changer has been installed, a new file is created in your root of your memory stick (ms0:/index.dat.bak).
Then go to VSHELL GAME MENU and launch 1.50 update.
Follow the instructions ...

He, das funzt ja wirklich .
Hab zum ausprobieren gleich mal Super Mario Bros. 3 draufgemacht .
Für Nostalgiker ist das bestimmt ne feine Methode, die alten Games nochmal zu zocken (Nes, Snes, Wonderswan, GB/C usw usw).
Allerdings werd ich wohl wieder upgraden, ich lebe lieber in der Gegenwart.
