A Guide to the Graphics of the Sega Mega Drive / Genesis


Notable updates are posted here:

  • March 8, 2021: Corrected some things on the Vertical Scaling page (thanks Sik):
    • Removed the statement “sprites cannot be vertically scaled.” Vertical scaling is technically possible with sprites since the sprite table can be updated each scanline.
    • The examples from Castlevania: Bloodlines and Battle Mania 2 don’t really show vertical scaling–nothing is being scaled. They work according to the same principle, though–mid-frame updates to VSRAM. In each example, sections of a plane are being vertically scrolled independently of other sections, something we can visualize as cutting and shifting.
  • March 5, 2021: Added a new page on Sprite Raster Effects.
  • March 1, 2021: Initial version of guide released.
