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 32-bit 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:
It reads plain or .prg files to any given address.
It can produce stand-alone self-decrunching files for the following targets:
Commodore VIC20, C64, C16/plus4 and C128 Atari 400/800 XL/XE Apple ][+ and //e
It can produce files for both "in memory" and "from disk" decrunching.
It handles RLE-sequences well, no packer is necessary.
It is able to link/combine more than one source file into the same crunched
target file.
Exomizer version 2 is still under development and are available as a beta
release. 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.
2007-01-28: Exomizer v2.0 beta 6 released
Changes since the 2.0 beta 5 release:
Bugfix: sfx -t 128 placed decrunch table at $0334, not at $0b00 where it is
supposed to be.
Bugfix: sfx -t 128 was unable to bank RAM/ROM properly.
Bugfix: Now works when compiled in a setting where unspecified char types are
unsigned.
Added experimental Oric 1 target to the sfx command. (not properly tested,
comments are welcome)
A complete changelog is included in the zip file. Download the 2.0 beta 6
release here.
2006-10-08: Exomizer v2.0 beta 5 released
Changes since the 2.0 beta 4 release:
New option -f to the mem and level sub commands that enables forward crunching.
Added a forward decruncher contributed by Krill / Plush.
Fixed a bug that made the sfx sub command fail on big endian architectures.
Added a dasm syntax version of exodecrunch.s.
Changed exodecrunch.s to support literal sequences by default.
A complete changelog is included in the zip file. (download removed)
2006-07-08: Exomizer v2.0 beta 4 released
Changes since the 2.0 beta 3 release:
Change email address.
Don't use setjmp/longjmp due to obscure bug when building using mingw with -O3
-fomit-frame-pointer.
Add multipass functionality to the assembler in order to be able to do more
complex things in the decruncher source.
Fix the sfx decruncher to work for a wider range of i_load_addr values.
Add optional offset,len for raw command file reading.
A complete changelog is included in the zip file. (download removed)
