PSPsetX v0.2 for PSP Firmware 2.0 Owners

[Insane1]

I am using firmware 2.0 just so I can play GTA, If I Downgrade to 1.5 and then use pspset to change it to 2.0 can I paly all the 1.5 homebrew and gta?

sry i'm a noob I just got my psp a month ago

No. GTA uses an encryption that 1.5x can't read.
And to my knowledge, Sony changed the encryption AGAIN when they released 2.60

I don't know why anyone would be concerned with downgrading anymore when you get alot more flexability with 2.0 and still have homebrew. I thaught that was the main reason for downgrading in the firstplace to keep the homebrew and nothing more. Its cool that it was created but a little late in the scene to really be any use at least for me, I would never risk the downgrade myself even though theres hardly a risk, theres just no point.

With 1.5 you can run ISO's, with 2.0 not

May I ask where to get this for Firmware 1.50? Just downgraded using this from 2.0, tried using KXploit on it, but says "Wrong PSP Version." I'm sure there is one somewhere on the net.. Wanna play the 1.52 + Games. Oh, and this works fine on Firmware 2.0.

Here A Thought If U Use Setx And Set Your 2.o Psp For 1.0 To Trick It...you Will Notice When U Insert The Umd With Firmware Update(anything Higher Than 1.0..gta Is 2.0 And Streetfighter Alpha Is 2.5) The Game Will Propt You To Upgrade Right So If Someone Made A Setx Like Program For 2.5 Or 2.6 You Thenuse Ta Exploit Load Your Eboot Loader Set Firmware Tweaks To 1.0 (triking Your Psp 2.6 To Think Its 1.0 Ok..) Then Put In Gta And Update Too 2.0 And Poof You Went From 2.6 To 2.0 From There You Could Use The Downgrader Tiff Exploit After Your Back To 2.0 Downgrade To 1.5

So From 2.6 Right Down To 1.5 All We Need Is For Setx To Work On Gta And Ill Try This Method

Alright I have a 2.60 PSP (and I regret buying one if it weren't for the snazzy white color and Sharp LCD)

My friend and I are trying to figure out how safe it'd be to run PSPsetX on it to downgrade the 2.60. Now I'm not willing to forfeit $250 to see whether this 50/50 chance works. So I've come to this forum in desperate hopes of an answer.

Here's what we plan to do:
1) Run the GTA exploit to run Homebrew for 2.6 (I already own the GTA UMD)
2) Run PSPsetX 0.2 (or would 0.3 be better?) to change the version name to 1.0
3) Run the PSP updater to 1.5

Will this work? I've lately read was this quote: The PSPSet App will never work (chances are it WILL brick your PSP). The MPH downgrader uses a special file called index.dat which contains the firmware version info. Sony has changed how they store the formware version info in later versions so it's not that 'simple'

Thanks SO much for your viewing and possible replies - they are GREATLY appreciated!!!!!!

BTW: You can use a 2.6 emulator on a 1.5 to run GTA

This is pretty common knowledge, so just keep this incident in mind the next time you're tempted to be condescending to other people's "noob-ish" questions (!_!)

The gameboot.pmf is the movie file that plays whenever you start a game eboot. PMF stands for PSP Movie Format, and is a proprietary format created by Sony. There are programs that give you the option to change this file, but the PSP actually requires this file to be in a pretty specific format and conforming to equally specific paramaters, so if you try to change it and make any mistakes, you will almost certainly end up with a PSP that won't run games and will be as good as bricked. Although your PSP will <i>technically</i> run without a gameboot.pmf or even with a bad one, since the PSP plays that video everytime it trys to launch an EBOOT, it won't be able to load any programs if it's missing or bad. That means that if you make any mistakes, there isn't any homebrew that can help you reverse it, because no eboots, including homebrew, will load.

That having been said, I don't know of any publicly available software for making pmf's and I've also never heard of anybody being able to successfully change their gameboot. Not to say that no one's ever done it, just that I've never heard of it.
