Monster Hunter Portable 3rd HD VER

If you're new to emulation first thing you should understand is that while emulators are legal, they can easily be closed down when mixed into any shady/illegal activities, hence if you would actually read the rules before posting(which is a good thing to do before registering on any site:]) then you would already know you shouldn't even ask about downloading commercial games as it's illegal.

We only deal with legally obtained games here, meaning dumping games from original umd's(good to add that in few countries it's actually illegal to make/own game backups) and/or using games downloaded from psn in form of pbp files. Eventually demos and homebrew which are often shared in many different places around the net.
------------------

If the above is clear, now about obtaining both of the things you asked, the game itself ~ HD version of MHp3rd is actually a ps3 game(or to be exact a minimally enhanced psp game released on ps3 aka lazy port made for extra cash), so you have to buy the game and either dump the eboot.pbp file using ps3 with custom firmware or extract the game using pc bluray drive(not all pc bluray drives might actually support reading ps3 discs, lite-on does I guess) and a handy program linked in the first post of this thread. Later you can also extract the pbp file to get an actual iso out of it, if you care about the english patch, but the game itself will run from pbp file just fine.

As for ppsspp always download it from official site or your mobile device shop(ie. google play on android) the top of that site has last major releases aka cherry-picked versions, the bottom of the page has most recent builds automatically updated whenever anything in the emulator code changes which usually is an improvement, but at times it can be regression, so if you're not interested in testing stuff might as well use only the top ones.
