Einar Saukas, the author of ZX7, has recently released ZX0 https://github.com/einar-saukas/ZX0 It compresses more than ZX7, and is faster uncompressing. My own test with CPCTelera: Input file: 952 bytes ZX7b:...

I've also added ZX0b, the backwards version of ZX0, which is similar in speed and compression ratio to normal ZX0 (depends on data). There is only one little problem with...

>czx7b | --compressor-zx7b - Use ZX7B compressor (Default). -czx0 | --compressor-zx0 - Use ZX0 compressor. I've changed the parameters for cpct_pack for a more rational: >-c | --compressor [method] -...

Regarding ZX0 compression time, I've done some testing using cpct_pack with text data as input. (my PC is a Core 2 Duo 3GHz running linux)  ...

I've updated ZX0 compressor to the latest version, released some hours ago. It fixes a bug in the "prefix" parameter, which is not used by cpct_pack but it's a very...

ZX0 has 6 decrunchers: Standard (69 bytes), Turbo(128 bytes 20% faster) and Mega(408 bytes 25% faster), each of them with normal and backwards version. ZX7 "offficial" release (https://spectrumcomputing.co.uk/entry/27996/ZX-Spectrum/ZX7) also had...

I've changed all the zx0 decruncher files, removing the _s tag of the name. I've also added a basic [ms] count.

I've been working on this idea for an example of direct decompression to vmem:  I've generated a .bin file with: >cpct_img2tileset -m 0 -of bin -scr -nt -th 200...

Ok, I found what I was doing wrong, now I can correctly compress files using compression.mk

I added a table and chart to file compression.txt. I've done the tests with my own set of sprites, as I can't find any standard test set. ¿do you know...
