b724b206a3 Add frame dupe option based on internal frame rate - 
average speedup (x2 resolution, Core i5 laptop) -
RE1 (no frame dupe) - 138fps
RE2 (frame dupe)    - 143fps

With frame dupe enabled, some of the fade to black transitions
in Tobal 2 (interlaced game) no longer show, so leave it as
an optional core option
