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? :)

Well, that’s not a holy grail, that is Amiga

maybe to make it more reasonable I'd leave out the top and bottom and the crunch area blank, just add the graphics in the sideborders. I don't know how many sprites can you have on a bad line with sideborders open though. Actually, having a multicolor bitmap without badlines and sideborder sprites (like in last part of Time Machine) scrolling in all direction... has this been done before ?

A demo where you can set it in warp mode, even if it runs on real hardware.

Well, you're too late for that, somebody already did that in a recent demo, and it looked awesome :)

The 160x200 plasma is definitely very nice - great job there :-)
