- as for jarring scrolling... if we're not talking about using hardware scrolling (which is already quite tricky on VGA, especially for chained mode13, not mode-x), there are no simple yet fast solution in a palettized 8bpp mode, other than precalculating a 0.5px shifted image.
as for taking VGA hardware into account, 320x200 is obviously a double-scanned version of 640x400 mode, and 0.5px vertical scrolling is technically possible with CRTC Preset Row Scan (0x3D4 index 8) register, just line smooth scrolling is done in a text mode.
As for horizontal one, things got pretty messy, as Attribute Controller's Pixel Panning (0x3C0 index 0x13) regusters, which permit smooth scroll by 1 pixel in 16-color modes, must be even for 256-color modes (as the VGA feeds one 256-color pixel every two pixel clocks), and setting it to odd values in hopes for subpixel scrolling just messes the colors up on most VGA cards, as I remember. Addtionally, it will require reserving 8 pixels to the right for the scrolling overflow, and the resulting buffer just almost into 64kb available for regular mode13 (65536 / 328 = 199.8 lines), althought it's only one line less than 320x200 :) - isokadded on the 2023-12-02 20:01:40
