• MSX, MSX2, MSX2+ or MSX turboR
• 16K video RAM

• MSX-DOS 2

Run gunzip from MSX-DOS 2, specifying the gzipped file on the command line.

Usage:

gunzip [options] <archive.gz> <outputfile>

Options:

• /q Quiet mode, suppress messages.

  Suppresses the output of informational and warning messages. Error messages, however, are always output.

If no output file is specified, the archive will be tested.

Gunzip is free and open source software. If you want to contribute to the project you are very welcome to. Please contact me at any one of the places mentioned in the project information section.

You are also free to re-use code for your own projects, provided you abide by the license terms.

Building the project with some of your own modifications is really easy on all modern desktop platforms. On Mac OS X and Linux, simply invoke make to build the binary and symbol files into the bin directory:

make

Windows users can open the Makefile and build by pasting the line in the all target into the Windows command prompt.

To launch the build in openMSX after building, put a copy of MSXDOS2.SYS and COMMAND2.COM and some GZ files to test with in the bin directory, and then invoke the make run command.

Note that the glass assembler which is embedded in the project requires Java 7. To check your Java version, invoke the java -version command.

With very minor changes (replace '&' with 'AND' in expressions) the source code also compiles with with compass and probably most gen80 compatible assemblers.
