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

File compression
