DevHook UMD Version v0.41d (Play Newer UMD Games on v1.5 PSPs)

Probably.. if not, Google is your friend

But then you don't really need sei to get rid of the corrupt icons, you can just put __SCE__ before everything, and put %__SCE__ infront of the folders that have the % symbol

Does this work with 1.0 PSPs through PSPbrew? I don't feel like upgrading to 1.5 :P

I'm going to cry now...

Like any new loader is going to work on 1.00, no-one seems to care anymore.
After seeing all MPHs loaders not work, UMD emulator, fastloader, etc... None of them seem to work on 1.00.

The best we have at the moment is Devhook v0.22.
I found this was the ONLY way I could play Lumines on a 1.00 PSP. (usually requires 1.50)

Devhook 0.22 will not play many (any?) games directly from the UMD though...

I'm a brand new 1.5 user thanks to the new downgrader, and I'm experiencing some difficulty installing the firmwares. I have the files in the correct placements, and when I run the firmware installer it detects my DATA.PSAR, but I get an error saying my memory stick is full, or it cannot create an "out" folder. Note that my mem stick is certainly not full. Any advice from the pros?

I know in the readme it says 2.6 and above not tested, but can i use 2.6 with this? I rented Daxter and i wanna play it, but i dont wanna upgrade to 2.6. Can i put 2.6 on the same way as 2.5? I would just do this right?

Copy the 2.6 data.psar to the root of my mem stick
Load the Firmware installer
Install the firmware to devhook

Wait, then reset
Load Devhook with Daxter in the drive


Would that work? I hope so.

Harshboy,
That won't work. 2.6+ have a different encryption so they can't be dumped YET! However, the encryption keys are stored in the kernel memory space, and as you know 2.6 recently got a kernel exploit, so they keys are going to be found soon and DevHook will work with 2.6+.

reekoy_3,
You have to have around 19-20MB free to install just one firmware, and about 36MB free to install two.

mog,
Use 0okms 1.0 to 1.5 upgrader and downgrader thing. Or just upload to 1.5, there's nothing to lose besides not needing to kxploit homebrew, but most homebrew comes kxploited nowadays.

Actuelly. I dont know where you read 2.6 wasnt tested, Its known that 2.6 firmware wont work with this, Its been tested bro, But there working on an updated version that will support higher firmwares as we speak tho

I know I could do that, but in a couple of days I will be installing the UP Modchip in my PSP anyway.

That still doesn't mean I am going to give up on fw 1.00.
I still plan on finding a solution for getting MPH UMD Loader and DevHook (higher than 0.22) working on fw 1.00 PSPs.

I don't like the idea of updating to get round the problem.
It is not be impossible to get these programs working on 1.00, it just requires time and a little trial and error.
The problem needs to be fixed, not avoided.

There is no point to having a 1.00 PSP. I may just think this because I am a 1.50er but it's not like you're a 2.71 and can't downgrade right? You could easily just upgrade to 1.50 right?

EDIT: I guess it actually doesn't matter for you because you are getting a modchip soon but for other people why wouldn't they go 1.5?

[jwilds73]

I just did this and it works great. Now I can have the best of both worlds without a mod chip. Lets hope the modchip allows the developers crack the latest firmwares and allow them to run.
