My coworkers and I had a ton of fun playing Medieval Mayhem on a real Atari 2600. Unfortunately, we no longer have access to the original hardware, so we decided to buy a pair of 2600-daptors and play the game on Stella instead. The game works, but there's a noticeable delay between using the spinner and the paddle moving — not so high that the game is unplayable, but clearly not as smooth as the real thing. If you bump up Stella's framerate manually, the latency disappears but the game runs at breakneck speed. This happens with the mouse as well, so it's not just a 2600-daptor/USB/driver problem.
It almost feels like when the game is running at 60fps (the normal framerate), the input and display refresh are actually capped at 30fps, even though the animations and music play at the correct speed.
Is there any way to fix this issue? Thank you!
