Well the PSP homebrew scene is in a bit of a slum, maybe he doesn't feel like putting the work into it because the majority of people are just going to use it to pirate games.
Very true, theres defiantly more iso players (people who hacked there psp just to play isos) than homebrewers/developers.
Honestly sony ignored the psp for ages, there first attempt with the 2000 was to take away the 1.50 kernel, pandora battery was born. Secondly they released the 3000 w/ the new motherboard, supposedly un-hackable, what lend to that failure? The shitty games being released.
So now we have the Go, no more UMD, all content is downloaded. But we still afaik have usb access, which will give access to te game file(whatever u download) & then probably people will find a way to hack those & host them all to play. I ain't sure how CFW will come about? Even if it does?
I don't think this will be the last cfw though.
