scroll right down to see the PSX2PSP converts and official PSone Classics
the perm patch can only be used on some PSP's but I assume yours should be fine
P.S. Popsloader is not required for PSone Classics, but may be required for some PSX2PSP converts and may take a few attempts to get the correct pops version via trial and error and most popsloader guide lines are for older firmware versions of the PSP and do not work the same on later versions of the PSP firmware, best to start with the newest pops version and work your way back as newer versions also have extra features supported like free scaling and more customizable controls, especially the later is a must and you are are stuck with less buttons than a basic digital only PSX pad has but that thumb stick that a basic digital PSX pad does not have
