Hey, Iv Just Joined The Forums Here At QJ.net.
I Have Just downgraded My PsP From 2.6 >> 1.5 and have managed to get DevHook up and running on 2.71 (WooHoooo)
I Also Have some ISO Files. But im not sure how to run them, Such As where i need to put them on mem card, or if i need to downgrade to 1.0 Firmware.
I Have Seen Videos From YouTube with someone testing this downdate and then choosing out of the large amount of ISOs in the memory card menu under the game area.
Cound Anyone Give me a Link to an article about this or maybe give me some hints.
