We have seen developers bring PlayStation emulators to the PlayBook before but now we have another milestone. BBIN.in spotted developer xSacha showing off PPSSPP running on his BlackBerry 10 Dev Alpha. That is right he got the PPSSPP PlayStation Portable (aka PSP) running on the Dev Alpha. I checked the PPSSPP project homepage and it confirms the BlackBerry 10 beta port and it is even available for download and sideloading if you are brave enough.
The website is also kind enough to have a game compatibility list though it isn’t very long. You also need to find a way to get your “legal” PSP games to play them. Good luck yea brave of heart! Otherwise you can just check out the demo video below:
