Holy Grails

I've been wondering about them, with some having been finally discovered, others not yet, and some probably going to remain in the realm of the impossible forever.

I'm speaking of things like:
- 320x200x16 graphics without restrictions
- Crash-free all-direction hardware scrolling
- Digi replay of 8-bit samples at one register write per sample and without requiring cycle accuracy

on standard vanilla hardware, of course.

Some examples of discovered grails are:
- Cube rotating at 50 fps about 3 axes
- The 9th sprite (with some restrictions)
- On-the-fly standard GCR block read+decode+checksumming

As for definition, they all satisfy some measure of being perfect or optimal or being possible after all, with no further improvements required, possible or necessary. But i'm not so sure if that definition holds water with regard to some of the examples i listed. :D

The question is, what other Holy Grails are there, already discovered or still elusive?
What are your pet grails you've been chasing after for decades or have found eventually? :)

Yes, that IFLI-part with 26 char lines! Though I'm not sure wether the 26th charline full of bitmap gfx was a world first in this demo or if it was done before, then most probably not as part of an IFLI piccy.

Now making all the rasterlines of the 26th charline fetch new VRam colours would *really* be a holy grail ;)
