I've been out of the PSP custom firmware game for a while. I've been running custom firmware on my PSP since the days of Dark Alex. I've recently started looking back into custom firmware, but the last one I have on my PSP-1001(non-TA-082) is 5.00 M33-6. Frankly I'm confused with all the choices around. Can someone point me in the right direction for the latest stable custom firmware for this? Thanks.
