www.psp-hacks.com to me = good source for firmware eboots....the forums are iffy on the material they present in terms of accuracy and depth....if you want a more technical website to visit, try www.maxconsole.net under the psp forums....though any forums you'll go to you'll just read a lot of repeated threads whining about downgrading (failed attempt from incompetence or if they upgraded to 3.10 and want a downgrader now)....but it should be good for you if you're starting out to learn stuff about a psp. My advice is to keep things simple and try not to go overboard on customizing a psp @ the beginning unless you know exactly what you're doing and always read read read read before you do anything. Not because some person on the internet said to go ahead....bricking a psp is a pretty easy feat for someone unfamiliar with the psp scene but once you're semi-familiar with it....it's almost impossible unless you're not careful.
