Z80 Coding - File compression when your game doesn't fit in memory

[@0MVR_0]

instead of compressing individual bytes,
mutate the abstraction to count associated information.

A sliding zipper/unzipper reads in linear form,
so the joint probability is the frequency of a byte to the next.

I'm afraid the audio is terrible, I can barely understand you listening on Smartphone. But anyways, congrats for the content :)

that'll be my accent :)

[@juniorcomsono]

@@ZXRetroGaming I'm terms of your accent I felt it pretty okay, for me it was more some sort of noise in your microfone :(

[@ZXRetroGaming]

@@juniorcomsonothat’s unusual, I don’t normally get complaints. I use a lav mic

Nice video. Do you have links to the resources used?

[@ZXRetroGaming]

The decompressor was on uniabis GitHub, the compressor I think was from lz4 on GitHub. Will check in the morning.

[@ZXRetroGaming]

I downloaded the compressor from here : sourceforge.net/projects/lz4.mirror/

​@@ZXRetroGaming Thanks. I have the same problem you had where I need to decompress in lines, not all at once. My current routines decompress one character at a time. My decompress is slow, but efforts a lot more control. If L4Z compression is better, might be worth a try. But I have a lot of short strings that probably won't compress well with this method.

@@SafePit yeah I've looked at the decompress routine to see if I could get it to skip newline characters so it doesn't break the display but don't think I can get it to do that
