Using my PSP 1000 series..When I turn it on..hit the select button..I get the VSH Menu and can see that I am using the M33 driver. Yet, sometimes I see people saying they are using M 33-6 (?). Where would I look to see if I in fact am using this as well? Sorry for all the Pandora battery questions..I'm going through menus..doing all kinds of things..toying with it.. Just haven't figured everythingout to run some of these ISO/CSO's. HoustonTX224
Go to your System Information under the System Settings, you should be able to see your current firmware.
