Portamos

Portamos is a portable, CLI based toolkit for working with AMOS Professional files on modern systems. The name is a play on portable AMOS.

It is bidirectional as you can both export and import to and from these now old formats. You instead work with JSON, text, PNG and WAVE files and use portamos to convert them into Amiga formats, finally copying them over to real or emulated Amiga computers. When paired with an IDE like IntelliJ IDEA and a simple Makefile to build all assets it becomes a quite nice developer experience.

AMOS Professional is a BASIC-like programming language for the Commodore Amiga, developed by François Lionet. Programs are stored as tokenised binary files (.AMOS), and multimedia data is stored in memory bank files (.Abk).

You can also use it as a library for your Java programs and build your own tools for working with AMOS files.

It also adds support for working with IFF ILBM and IFF 8SVX files in standard Java ImageIO and sound APIs.

• Listing binary (.AMOS) files and save them to ASCII source (.Asc)
• Tokenising ASCII source (.Asc) into binary (.AMOS) files, allowing you to edit in favorite IDE

• Adding bank (.Abk) files into .AMOS files
• All official bank types can be exported to JSON and accompanying files in modern formats

  • AMAL (JSON + programs > .Amal)
  • Resource (JSON + sprite sheet .png or .ilbm + programs > .Amui)
  • Pac.Pic (JSON + .png or .ilbm)
  • Music (JSON + .wav or .8svx files)
  • Tracker (JSON + .mod files)
  • Work and Data (JSON + raw files)
  • Menu (JSON)
  • Bank sets (.Abs) exports into .Abk files
• Exported banks and bank sets can be reassembled into .Abk and .Abs files allowing for modern workflows
