Frameskip implementation

Hi guys. Ninja gaiden emulates near perfectly in graphics. But it is running in slo-mo. Please tell, is it possible to implement frameskip in this emulator?
I think it would sovle a lot of problems if it can be made.

Right click on the game, select "Open Config Folder", if you have custom config set for this game, you'll see a "config.yml" file, dont worry its just for this game and can be deleted.
Open it with Notepad++, look under Video section there are 2 options:

Consecutive Frames To Draw: 1
Consecutive Frames To Skip: 1

Play with these settings

It's not a bottleneck unless draw time is huge, so adding frame skip won't help in performance.
