I can't imagine that full screen would look good.

This emulator supports proper ratio of 1:1 if you use it in windowed mode and 2x full screen.

Anything else would look terrible in my opinion. Heck, I don't even like the feel of hardware scaling so I have that feature removed.

Also, I don't think this will run the Tales translation.

If you're looking for something easy to play, might I suggest Wonder Project J. Change the speed of Pina's movement to slow in the options menu and you've got a great time waster to enjoy.
