you got it confused. Its Witch on the holy night that will be getting english release this winter.
8th of december for Digital. And 27th of January for the limited edition physical(PS4 amazon link US import, switch amazon link seems to be down we dont know why)
Not exactly, with an NScripter interpreter you can run games written with NScripter (like Tsukihime).
For PSP games on Android I'd recommend PPSSPP.
I also had this problem.
Tried a lot of solutions and none worked.
On my laptop it goes full screen with black bars to maintain aspect ratio but on desktop it becomes stretched.
I found a workaround though using this software http://www.blacksunsoftware.com/screenmagnifier.html
Basically you can zoom in on the game window.
