Ok, Let me get this straight.
I have I 1.5 psp with devhook and customfirmware that enables me to emulate 2.71 via the mem stick.
Are you saying there is no point in this anymore is this "2.71 SE-B" is 2.71 but tweaked to have all of 1.5's strengths?
And if its better to change to this, how do it uninstall all that i have on it now?
