I've been playing through Dracula X Chronicles on PPSSPP, sold my entire PSP collection recently and about two days later got the urge to play it again so I stuck it on the G5A. It's a much nicer game to play with save states, particularly if you suck at Castlevania bosses like me!
I have 3rd Birthday and Silent Hill Origins & Downpour queued up too, although they don't run particularly well via emulation on the G5A unlike the above game which is flawless.
