koala otpimizing
Hi Everyone,
I know there's a c64 tool out there that helps with optimizing koala pictures for packing, but no idea what it is called. Anyone knows?:) Timanthes would do the job for me aswell with its nibble swapper tool, but is there a way to load/save a native c64 koala format picture with it ? *.prg doesnt works, what format does it expect to be .prg anyway ?:) |

Great :-)
So, let's see who creates the smallest file that displays these three pics (press space to swap ;) ).
Rules:
1) It has to be one file containing all three pictures
2) ANY form of optimizing is allowed
3) Final file crunched with Exomizer
Shall we set a date on which the file must be ready? |

I think it's better to come up with 3 exo-data files, that de-exo'd give the bitmap-data,colors and d800 color in the memory.
As simple as that.
Also, Im not sure I have time for this :) |

I don't have time either, so let's set the date for Xmas 2007 :-)
Also, just exo'd data isn't interesting.
For optimizing sake you might be right, but this doesn't leave room for exotic ways of storing a picture in the memory.
If this is the plan, I'm out, as it's no fun ;-)
I might just give it a go... some time.
First some other 'projects'. |

pre processing the file and then using custom compression would give optimum sults, but the lz based compresion isgood enough for most purposes |

I probably won't have time either, but why restrict it to exomizer?
Any runnable program that shows each of those 3 pictures should be allowed.
Some of those will be _slow_! ;)
Also I think it should be just one picture per binary.

Maybe it's time someone did arithmetic (de)coding on the 6502?

I always liked data (en)(de)coding, although it's not quite my field of expertice.
One of my experiments was plain Huffman encoding, but I quite when I had to find a way to store the binary 'tree' in such a way that the crunching actually produced a smaller file :)
Also, my knowledge of existing mathemetic algorithms is fairly non-existant. That's not handy, when doing stuff like this.
Just a brain fart: what experiments could you do with rotating data?
If you have data like:
.byte $00,$ff,$00,$ff,$00,$ff,$00,$ff, Rotating that 90 degrees would result in 8 bytes with the same value.
Easier to pack than a pattern... sometimes :) |
