There is a drop frame in scrolling games, like the screen is not well synchronized at 50Hz.
It happens on C64 and Minimig Core.

On Atari ST core the screen is perfectly syncronized in scrolling games, like Giana Sisters STE version.

Old minimig ECS Core is well synchronized, but minimig AGA doesn't.

The MIST does not drop any frames as it doesn't synchronize anything. It's not like an emulator where you need to sync the emulation with the video output of the PC it's running on.

I also see some stuttering with e.g. the Genesis core and my TV. But it's the TV that does the buffering and does the imperfect synchronization. The same core looks perfectly on other screens.

If there's a change between the ECS and AGA cores than the video timing might have changed slightly and you TV just handles it differently. But i must admit that i don't know much about the video of an Amiga.

Thank you Sorgelig for adding this feature!

I hope to try it out. I currently have hdmi out going to an s-video converter and some of the picture is cut off screen so I am mostly using it on a flat tv outside of this test on my CRT in case a setting could improve the cut-off. On my Component input, My HD Retrovision cable really shines! With all the great Mister addons like cases and even an RTC board, I am still surprised no one has a simple HD-Retrovision quality solution. Am I alone in thinking it would sell like hotcakes?

I have 90s VGA Computer Crts, (even a NEC mutisync), 80's Commodore monitors with 9pin RGB input, and both S-video and Component input CRT tvs and have yet to connect my Mist or Mister to them in an ideal way. I've made Atari cables to connect the serial to USB for disk loading, but prefer not to rely on my hack job for Mist and Mister. Maybe Console5 can put a DIY kit of all the parts needed together. Have any of you made a video making one?

I am open to PM if anyone has a good cable(s) to sell!
