Antiupdate
And the pictures show seplugins.
rite now in my ms folder only hav 3 folders
iso , mproot and psp . i don't see seplugins . [/u]
Yeap. Create the ms0:/seplugins folder, and make a vsh.txt (never used it, but I'd say it should be that) and add the path to the PRX, eg ms0:/seplugins/theprx.prx
Next, enable the PRX through the recovery menu.
