animation/vertex interpolation for 30 fps games

[NoZart]

Hi,
first of all thanks for the emu, it really rocks.!

I would like to ask if it would be possible to include some rendering interpolation at the cost of having one frame lag?
A few years back i saw a plugin for the PSX emulator which did exactly that, and it improved on the games a lot.

I know that there are lots of 60fps patches out there, but maybe you should consider it anyway, so that it is (sort of) a global solution?
