Gaming ISOs dont show up on the psp

[OmegaVitaminC]

i think it was after installing pops loader that my iso files stopped showing up on my psp.
cso files and psx games show, but my iso wont (cant compress it, even level one compression makes that game lag to the point where its unplayable).
is there some specific setting i must have in the recovery menu to make the isos show up?

what's the filename?

if it's too long or has unusual characters in it, then it wont show in the menu.
