google "evilsperm sdk" if you dont mind ubuntu virtual box setup..
what i did was grab both , add the psl1ght sdk image as a slave hdd.. so @ boot of the vm press f12 to select what hdd to boot from:
sony's hdd 1
psl1ght-v1 hdd2 , it takes up a LOT of room but the most complete dev set up i have found.
as for the lack of info there is some out there just takes a lot of researching also its hard to at the present moment as its all still growing and merging..
but if anyone wants my vm i made pm me its a 3gb microXP with 1.92 setup and all nessesery portable software.. ffox , 7zip , treesize and crimson editor.. lol i've even now set it up so i can right click a folder and open cmd ... type "make" and i get a self.. i just copy the self to usb then i do the rest outside of my vm .self to .pkg.. its the one i use the most.. gonna look at installing psl1ght-v2 into it when its been made stable.
