Unless you are trying to the the ps3 game the ps2 and psp should be able to be emulated on literally any pc.
Hell psp runs fine on most android phones as well.
You literally have to be trying to not find a way to play these games if you say they aren't easy to play. Fuck legality if the copyright hold is sitting on these games for no fucking reason
Shared doc are very rare, but I have used them.
My personal devices run Linux and windows, but I also use public computers running mac and windows. And in worse case scenario I note take on my phone as well
I might try this if no other options exist however.
