MAGL — MAG Image Loader for X68000

Version 2.02d (1993)

MAGL is a MAG/MAKI image loader for the Sharp X68000.

It reads MAG-format image data and displays it directly on hardware by writing to VRAM.

This program was originally developed in the early 1990s and is provided here in its original form.


Purpose of This Repository

This repository is intended to preserve:

  • MAG format decoding and rendering logic
  • Low-level implementation techniques on X68000 hardware

The source code is published as a historical and technical reference.


Policy

  • 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.

Usage

MAGL [switch] filename

For detailed usage, see the original documentation:

docs/MAGL.DOC


Notes

  • This program directly accesses hardware (CRTC, VRAM, IOCS).
  • Behavior depends on the X68000 / Human68k environment.
  • Some operations may affect system state.

Original Documentation

The original distribution document is included without modification:

  • docs/MAGL.DOC

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