Just a few short days after the landmark release of Devhook 0.50, Booster has once again updated Devhook to v0.51. And the amazing new addition in the latest version is nothing less than 3.01 emulation! While people couldn't have been happier, it was, in a way, expected after the original fireworks by none other than the Noobz crew.
While this should result in a lot of tinkering by everyone, for now, you probably will be able to check out PS1 games on your PSP if you're one of the lucky ones to have a PS3.

Anyways, I can bet that you'll all be dying to try this out. Well, what better than to link to our forums with a tutorial. And while it says that it's for Devhook 0.50, I've already confirmed that the same steps will work, even for the latest devhook. Finally, here's the latest release of Devhook and its respective SDK.

sadly the only psp downgrades past 2.80 you have to pay for, there is one 2.80 downgrade at http://www.psp-vault.com/Article800.psp. if you want the one you have to pay for you can find it at http://www.pspdowngrading.com/?hop=milleniumb. but ill be dammed if im gonna pay for something thatll be free in a month. modchips can be used but those will run you about $100 so ide just say wait. im still waiting for mine to run cheat device on vice city through devhook.

You can downgrade from 3.03
with the use of an unpatched (origonal Release) of GTA:Liberty City Stories and a special gamesave file to make use of an exploit to run hend. then you can run downgrader. good luck finding it last i seen was on ebay for $50.00
PSP

Off tops
All right, i was watching this topic a while and i noticed that some people asking about how to downgrade 3.3 and 3.4 and some advertising s**t. THAT'S OFF TOP I DON'T WANT TO SEE IT HERE ANYMORE! TO PREVENT POSTING OF THE QUESTIONS ABOUT DOWNGRADING: THERE'S NO WAY U CAN DOWNGRADE PSP THAT HAS VERSION HIGHER THAN 3.03!!! EVERY NEW POST ABOUT DOWNGRADING QUESTIONS WILL BE DELETED RIGHT AWAY!

devhook problems
i have recently changed my memory stick however all my downgrade seems to be not working even though i have the 1.50 version. ofcourse i have downgaraded my psp earlier on from 2.60

upgrading my psp seems the only option or should i process the devhook from square 1?
