You don't need to know if you need to ask
 Seriously, it is mainly useful for development and testing (exact same output in real hardware and in emulation) It isn't really visible without magnifying glass OCS/ECS can only scroll horizontally in lores resolution. If resolution is hires, minimum scroll amount is 2 hires pixels (=1 lores pixel). AGA introduced "subpixel" scrolling, minimum scroll amount increased, it is always 1 superhires pixel. For example Fire & Ice bottom section's "wave" effect uses subpixel scrolling. (lores screen but hires scrolling) http://eab.abime.net/showthread.php?t=93380 also includes some examples/special cases. |
