| Adjusting internal vsync rate for the emulated systems: where in the sources should I look? [message #1616] |

hello there
After trying to find the correct exact refresh rates for the systems Mednafen emulates, and not being able to find those for Gameboy, Lynx and others, I'm tired of ramdomly trying modelines and getting jerky horizontal scrolls on those systems.
I accept the "exact speed" approx Mednafen takes, but I'd like to alter the sources so I can force the systems into a EXACT 60.0000 HZ internal vertical refresh rates, thus using the same video mode for them all and getting perfectly smooth scroll at once.
As I'm not a Mednafen coder, I don't know the code, but I should be able to change it. Where can I find the variable(s) I'm looking for, developer people?
regards

The frame rate of the emulated systems is a side effect/derivative of the emulated system's video frame length; there are no single variables that control refresh rates.
What you propose would require knowing the exact average refresh rate of each emulated system, and using that value as the input rate(and 60.00 as the output rate) for the ratio in a sound resampler operating on the returned sound data from MDFNI_Emulate().
I don't wish to belittle your request, but...I have more important things to work on, so you're on your own.

(Err, I think I got those input/output ratios backwards. I'm far too sleepy now to think straight >_>)
