Falcom is filling the PC Engine section on PlayStation Network with Ys titles. Four of them. Three if you count Ys: Books I & II as a single "game." Ys: Books I & II will be available as a PSN download on November 17. The PSP and PlayStation 3 compatible file will cost 800 yen ($10).
While these games don’t have a scheduled release date, Falcom announced they’re going to distribute Ys III and Ys IV on the PlayStation Store too.
Even though Ys III and IV were released for multiple consoles, Falcom will probably upload the PC Engine version of both games on PSN. After all, there isn’t a Super Famicom section on PlayStation Network.
