Ys Seven PC Edition
Would it take much at this point?
Keeper of the Sacred Pork
Oath in Felghana (and Origin and most of the rest of the series) started on PC and went to consoles later (Ys 4 and 5 being the exceptions), but Seven was developed as PSP-only.
There is a Chinese port that will be released this summer, but it's probably not going to be high enough quality to be worth bothering with if their Zero no Kiseki port is anything to go by (broken audio, control issues, performance problems, etc).
