[Feature Request] Fast Forward Speed Limiter

Similar to the “Slow motion ratio” general setting, I would like to be able to limit the fast-forwarded speed to some factor of the real-time speed.

For example, I’d like to be able to set “Fast-forward ratio maximum” to 5.0, which would limit the fps of a normally 60fps game to 300fps. Currently, very efficient cores can run at incredible (35x +) speeds.

Kind regards.

It is your lucky day: https://github.com/Themaister/RetroArch/commit/9927294d371bb589621ff6651bde4688508ddcda

fastforward_ratio = <ratio> in config with this patch.

Thank you, Maister!
