Version 1.02a (1992)
TASIMASU is a tool for concatenating two MAG images into a single MAG file on the Sharp X68000.
It supports both vertical and horizontal concatenation.
Unlike simple image joining, this tool reconstructs the output while preserving the internal differential encoding structure of the MAG format.
This program was originally developed in the early 1990s and is provided here in its original form.
This repository is intended to preserve:
- MAG format internal structure handling
- Image concatenation algorithm based on differential encoding
The source code is published as a technical reference of the original implementation.
- The source code is preserved as-is from the original development.
- No refactoring, modernization, or feature additions are planned.
- This is not an actively maintained project.

- This tool operates directly on MAG internal structures.
- It does not perform full decode/re-encode processing.
- Input files must meet specific format constraints.
The original distribution document is included without modification:

The original documents are included as-is in Shift-JIS encoding.

This software is based on the MAG image format specification, originally designed by its respective authors.
This repository exists to preserve an algorithm.
If you are interested in the MAG format or its internal structure, you are free to read, reuse, and adapt this code.
