The Commodore 64 amassed a large software library of nearly 10,000 commercial titles, covering genres from games to business applications.
Applications, utility, and business software
The Commodore 64’s slow 1541 disk drive limited its suitability as a business computer, yet it was used for tasks like graphics creation, desktop publishing, and word processing. Info 64, the first magazine produced using desktop publishing tools, was created on and dedicated to the Commodore platform.
Popular graphics software included KoalaPainter, known for its graphics tablet interface, and Doodle!, a widely used drawing program. Desktop publishing tools like The Print Shop and "The Newsroom" enabled users to create signs, banners, and newsletters. Light pens and CAD software were also available.
The GEOS operating system provided a graphical interface akin to the early Apple Macintosh, with office applications and support for peripherals like printers and light pens. It gained popularity for its affordability and capabilities.
Music software included Music Construction Set and MIDI cartridges, with the modern Prophet64 cartridge offering advanced sequencing and synthesis.
Think back for a minute to the first program you ever saw on a Commodore 64. Chances are it was a game, if you've had a 64 for more than a couple of years.
By 1985, games comprised 60–70% of Commodore 64 software, driven by its advanced sound and graphics hardware. Over 23,000 unique game titles were released.
The Commodore 64 shipped with BASIC 2.0, limited in accessing advanced features, requiring PEEK and POKE or extensions like Simons' BASIC. Commodore opted for BASIC 2.0 to reduce costs.
Development tools included assemblers like MIKRO and compilers for C and Pascal. Game creation kits like SEUCK and GameMaker were popular.
Modern-day development tools
Current tools include CBM prg Studio, Relaunch64, and assemblers like Kick Assembler and cc65.
Retrocomputing efforts
Preservation efforts involve transferring software to modern media and developing emulators like VICE. The GameBase 64 project catalogs nearly 29,000 titles.
