Does anyone know if cxmb works on 3.71 m33? I upgraded my rcos using a 3.60 tool but when I tried booting my psp I get a black screen. I've been staying at 3.52 m33 for the moment b/c I can't get it to work. Also, if anyone can confirm that prx launcher v1.0 works on it too that would be helpful. Thnx in adv.
