Data Compression

Wikipedia says :

In computer science and information theory, data compression or source coding is the process of encoding information using fewer bits (or other information-bearing units) than an unencoded representation would use, through use of specific encoding schemes.

So be it.

Compression ? In my CPC ?

More often than you may believe.

The power of CrossDev

It was common to use a 16 bit computer like an Atari ST to get stronger compression. Today it is possible to get various compressors which are running on a PC platform and produce binary files which can be decompressed on Z80 computers.

Xyphoes Fantasy is a noteable example. The data is compressed and it was generated on an Atari ST.

Examples for modern CrossDev compression programs with Z80 decompression routines are

• Bitbuster
• Exomizer
• MegaLZ
• Pucrunch
• ZX7

File compression

• Cheese (Antoine Pitrou)
• Columbia (Robot PD)
• CPC_T (Madram)
• CrownCruncher (Crown)
• FlowerCruncher (Roudoudou)
• LZ48 (Roudoudou)
• LZ49 (Roudoudou)
• SQ23
• Turbocruncher (Elmar Krieger)
• Turbo Imploder (Crown)
• Zenith

File decompression

• LZ4 (Roudoudou)
• NLarge (FG Brain)
