Render Duplicate Frames to 60 Hz Option

[LunaMoo]

This option has nothing to do with FPS modifications, it's duplicating frames for PPSSPP to have something to display(instead of waiting) every time a standard 60hz screen refreshes, in the past this was only active via post process flag since animated shaders require it, however it turns out some people with outdated fixed sync displays have problems running PSP games without some stutter and weird things, this option helps them.

PPSSPP will never have option to double FPS or anything like that, this can only be achieved by patching the games itself since each one works differently, we have a thread with some patches on our forum, but a lot of them will have a negative impact on gameplay, changing physics, timing etc. some of them break games much more, so when using them, don't report issues as this just wastes everyone time, for many of them you will need to disable the cheat, restart emulation and reload from standard in-game savedata to get rid of potential issues.
