Exomizer 2 website

Exomizer is a program that compresses files in a way that tries to be as efficient as possible but still allows them to be decompressed in environments where CPU speed and RAM are limited. For some popular 8-bit computers using 6502 compatible CPUs it can also generate executable files that decompress themselves in memory when run.

The exomizer program itself is a console application written in ANSI-C.

Exomizer operates in two major modes. It has a raw mode that compresses plain files and produces plain files. This mode is used by the raw subcommand. All other subcommands use the second mode. It requires all source files to be targeted to be decrunched at specific addresses in the 16-bit address space of the target computer. In this mode, no file can be larger than 64kB since all data must be addressable using 16-bits. The targeted mode has the following features:

Exomizer version 2.0 has been released and is available for download. Included in the downloadable zip file are the source code and precompiled binaries for DOS and Win32. It also includes a makefile for Gnu make and gcc so it should be easy to build on any system where these tools are available.

Any suggestions, comments and/or bug reports can be sent to me, the author.
