I loaded both games and they work just fine on a stock VICE emulator. Just takes time to load. Here’s a video of both Turrican games loading, and I also use Warp Speed at times to make it load faster. I have actions mapped to my controller to warp speed and switch joystick. One note is that I did change the extension from .tap to .t64, but it’s just because I use that extension for my tapes.

EDIT: Checked the vertical scrolling, not in the recording though. Just realized that was the most important part of your question! When I played the first level for a few minutes, I went left and right then up and down the level and it was smooth as silk!
