PPSSPP for Windows Phone (8)?

[Henrik]

"Threaded" (not to be confused with multithreaded) interpreters generally get you around 2x over a regular interpreter, while JITs get you 10x+. And it's a much smaller market and the only one with this problem (well, iOS too but that doesn't even allow emulators), but it's indeed pretty likely that at least some games would be fairly playable on fast Windows Phones, maybe even with the current interpreter.

Doing the DX11 port of the GPU emulation might probably be more work than getting the basics of such a CPU core running though..
