    Can anyone tell me how to play ISO on 2.50? Or do I have to downgrade? Please tell me how I play ISO games on 2.50 or less.

    Thank You.

    You cant play em on 2.5 you need to get the easy downgrader and an unpatched version of GTA:LCS. There is also a new downgrader u can use that is gta-less, you will need to upgrade to 2.71 for it to work tho. After you downgrade download devhook it can load iso's and emulate 2.71. all files can be found it http://www.psp-hacks.com There is a tutorial called Downgrading and Devhook and Compression. That tutorial will help you with devhook. But the 2,71 downgrader includes a tutorial on how to use it. and the easy downgrader walks you through the whole process. but like i said earlier u need an unpatched version of GTA:LCS for the EZ Downgrader.

    Your answer is very confusing to me. It's my first time to do this so I think you need to tell me in easy simple terms eg. step 2 step guide.

    from hex :
    1) you need to downgrade your psp to 1.5 to play iso's
    2)theres two ways you can downgrade - 2.5 downgrader (requires grand theft auto umd)
    -upgrade to 2.71 and downgrade (doesnt require gta)
    3) before you can downgrade you need to check if you motherboard can be downgraded so check http://forums.afterdawn.com/thread_view.cfm/369035 with this guide to see if your motherboard is compatible and if you are doin the 2.5 downgrade, also check you have the right gta umd
    4) if you want to do the gtaless method upgrade to 2.71 firstly in your PSP/GAME folder on your memory stick create a folder called UPDATE and download this file http://www.psp-hacks.com/file/525 and put it in there, then go to game on your psp and run the update :)
    5)if you need more help come back and well give you more steps

    Files :-
    easy 2.5 downgrader:- http://www.psp-hacks.com/file/605
    2.71 downgrader :- http://www.psp-hacks.com/file/753

    phew lol

    actually the same bricking possibilites apply as the 2.71 downgrader is a port of the 2.5/2.6 downgrader.

    I don't get the 2.71 downgrader thing. Do I need another psp with firmware 1.50 or I don't have to?

    PS Is there a UK version of 2.71 update? Because there is US and JAP version only and I actually live in UK with a uk version PSP. D you think the uk version will work on us one?

    YAY! I use the 2.71 downgrader and it works! My psp is now 1.50! Thanks. Also you can use the US version of the 2.71 update to work on UK psp's.
