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? :) |

I take it that the 2 mcol sprites of course use the same 2 fixed colours per line? So they would provide 4 colours total, to each line at most. |

Correct. Each column has access to between five and eight sprite colours; here's a chart:
+----------+---------------+
| |1 2 3 4 5 6 7 8|
+----------+---------------+
| $d025 |X X X X X X|
| $d026 |X X X X X X|
| $d027 |X X X X X X |
| $d028 |X X X X X X |
| $d029 |X X X X X X |
| $d02a | X X X X X X|
| $d02b | X X X X X X|
| $d02c |X X X |

HAHAHAHAHA
Dammit, I did think about swapping the last two lines (more of a diagonal stripe that way), but wanted to stay faithful to the allocation Reutastic actually usedÂ… |

You accidently clicked on "ignore all posts from this user". You can revert back to previous somewhere in userpage I think |
