Try downloading this file: http://dl.qj.net/PSP-Upgrader-Downgrader-Lite-PSP-Tools-Utilities-(on-PC)/pg/12/fid/14220/catid/193

but if not then you'll just have to w8 till one is released, keep checking http://dl.qj.net/ for updates. Unluckily for you, if you had've stayed at 3.50 you could downgrade straight away.

Anyway once ur on Version 1.50 upgrade to a custom firmware such as Custom Firmware 3.72 HX-1 http://dl.qj.net/Custom-Firmware-3.72-HX-1-PSP/pg/12/fid/15067/catid/163.

Once u r on this firmware just stick ur .ISO file in the directory /PSP/ISO. Go on ur PSP, Games, memory stick and play ur game, PS. make sure u have a UMD in at the time.

Hope this helps
