Building from source

The source code is available to learn from, laugh at, or ignore.

Source code version 1.1, released 2018-06-16: dunjunz-1.1.tar.gz.

Git repository: git clone https://gitlab.com/sixxie/dunjunz.git

The build system very much depends on a Unix-like environment, and on many commonly-available Unix tools and libraries. You'll need a C compiler, the SDL_image 1.2 development files, Perl, asm6809, bin2cas.pl, and dzip.

Building the disk image requires the decb tool from ToolShed.

If all that's available, just type make. make clean to tidy up.

The original BBC Micro version of Dunjunz is by Julian Avis, and copyright Bug-Byte, 1987. Bug-Byte eventually came Grandslam Interactive, which was dissolved in March 1999. It is most likely that the copyright has returned to Julian Avis.

This rewrite is an homage to the original, and was not created to sell—though I may make at-cost copies available from time to time. Consider it as simply a proof that a Dragon version could have been released at the time.

No code from the original was used, and all design decisions are based solely on observation. However, certain presentational elements were derived from the original:
