Yes a few people have this issue, it ran with no shaking on my emulator. I just released a new version that will hopefully address some issues that others are having.
Thank you for the update, the new build has eliminated a number of the scanline issues but still some remain along with the visible shaking. In the new version standing still seems to be mostly okay but walking (on most screens) and jumping still seems to invoke issues.
You should be able to see the issues in Stella if you're running the newest version of 6.7. Here is a post explaining the scanline issue better than I can.
