Differences between photoshop and psp

Ok i'm not sure if this is allowed. And i'm really sorry if this isnt, so feel free to delete. But the trouble is when i'm trying to figure out whether a tutorial i've made in ps is translatable to psp. So i know some functions which are on ps but not on psp, but could someone please identify a few more so i know...and can put it in for future tutorials i make.


PSP
-Does not have selective colouring
-Has flood fills

As you can see, i dont know much about psp...any help is appreciated.

and once again, i'm truly sorry if this isn't allowed.
