Has anyone tried the PC1512 driver on a real system? If so, I'd like to get feedback on a couple of details.

Does the border (overscan area) of the display stay black when switching from graphics to text mode, such as when viewing inventory (TAB key)? The border flashes white briefly in PCem, which may be an emulation issue, but I have a relatively easy fix if the issue applies to real systems as well.

Does the screen shake look okay? Due to limitations of the hardware, I use the display start address instead of display position, which is not ideal but better than nothing. I'm not sure that emulators get it right, and a video clip would be great for verification, if possible. SQ2 has some screen shaking near the start of the game when Roger enters the shuttle and when the shuttle crashes on the planet.
