Feature Request: Higher overclocking options for Genesis and Add a similar feature for Sega CD Games

[aorin1]

I've never had so much fun playing Road Rash 1 through 3, specially the latter, since the overclocking for the 68000 CPU was added, it literally doubles the frame rate, since the vanilla option shows how choppy these games run, breaking the fun factor and specially the gameplay. It also helps a lot the other simulation games, Steel Talons still run slow at 200% overclock, but I feel all these can benefit from higher OC options can make all those CPU-heavy games run so much better.
I also tried the OC for the Road Rash (Sega CD) but it doesn't seem to help that game, so I figured it possibly uses the Sega CD co-processor to render that game, though I'm not sure.
With the above, I wonder if it's feasible adding higher OC options and a separate one for the Sega CD?

I just captured this gameplay showing the vanilla vs 200% OC:

Overclocking the 68000 is a good feature.
Road Rash and Super Hang On has better frame rate , but crash some others games.

Current limit of 500% seems enough for closing?
