Re: [Freedos-user] New AMB - with compression

I've made an AMB edition of my latest book, Overscan: Stories From Beyond the Screen's Edge. I incorporated MVCOMP into my workflow to make a new version, which you can find on Mateusz's site: http://mateusz.fr/amb/ MVCOMP cut down the size of the AMB edition from 66K to 38K. Overscan

Re: [Freedos-user] New AMB - with compression

Hi Mateusz, The compression is a crude, back-referencing algorithm of my own design, called MVCOMP http://mateusz.fr/mvcomp/ Its compression rate is not spectacular, but it is not much worse than deflate, while being significantly simpler and faster. I assume you enjoy designing algorithms,

[Freedos-user] New AMB - with compression

Last night I published a new AMB specification and new toolset (amb, ambpack and phpamb). The major change is that AMB files can now be compressed. The compression is a crude, back-referencing algorithm of my own design, called MVCOMP . Its
