Thank you!

Thanks to your help I removed the jerk by increasing the emulation speed to 1.02 to match the 60.01Hz display rate of my screen. I tried 1.01 first which was a lot better but still had a jerk every now and again




The throttle is still turned on so it's authentic gameplay.

It's nice to see it finally running smoothly.

Neo Thunder doesn't have any sound or music so no worries about the audio 🙂
