Ultima I–III EasyFlash

This repository contains the source code to build an EasyFlash cartridge image from the original Commodore 64 disks for:

• Ultima I
• Ultima II
• Ultima III
• Ultima 0 (Akalabeth)

Features

• Import and export save games
• Minor improvements and bug fixes

Required tools

To build, you need:

• cc65
• Exomizer 3
• c1541 (from VICE)
• cartconv (from VICE)
• Python 3.5 or newer
• GNU Make

Building

1. Create a folder named disks/.
2. Place your original disk images (e.g., d64 or g64) into disks/ using the following filenames:
   • Ultima I: ultima-i.d64
   • Ultima II: ultima-ii-a.d64, ultima-ii-b.d64
   • Ultima III: ultima-iii-a.d64, ultima-iii-b.d64
   • Ultima 0 (Akalabeth): ultima-0.d64
3. Run the build:

make

The resulting cartridge image file will be written to: build/u123-easyflash.crt

Bugs / feedback

The games have not been tested thoroughly yet. Please report bugs or suggestions to drunella@gmx.de. For Ultima II and Ultima III, better versions already exist. I plan to improve these builds in the future.
