Iowa Jack and the Crystals of Chaos Brings a New Adventure to the Commodore Plus/4

Ricky Derocher releases Iowa Jack and the Crystals of Chaos for the Commodore Plus/4, adding another new title to the remarkable ongoing homebrew scene for Commodore's commercially unsuccessful 264-series computer.

Commodore's Plus/4 continues its remarkable second life with Iowa Jack and the Crystals of Chaos, a new 2026 game from Ricky Derocher. The title was added to the Plus/4 homebrew feed on 14 September, giving owners of Commodore's commercially unsuccessful 264-series computer another piece of software that simply did not exist during the machine's original lifetime. The Plus/4 has become one of retro computing's more interesting rehabilitation stories. Introduced in 1984, it offered a different TED graphics and sound architecture from the far more successful Commodore 64 and included built-in productivity software intended to give it a more serious identity. Unfortunately for Commodore, customers generally wanted compatibility with the enormous C64 software library rather than a new incompatible platform. Publishers followed the audience, leaving the Plus/4 with a comparatively thin catalogue. Modern developers no longer need to care about mass-market installed bases, which turns that historical weakness into an attraction. Choosing the Plus/4 today means exploring hardware that professional studios had relatively little time or incentive to master. Iowa Jack and the Crystals of Chaos fits into a growing modern catalogue of puzzle games, platformers, adventures and conversions designed by enthusiasts specifically for TED-based machines. Public information surrounding the new game remains relatively concise, so it would be irresponsible to manufacture a detailed feature list or elaborate story beyond the title and confirmed target platform. The important news is the release itself and the continued health of Plus/4 development. Ricky Derocher has already worked across several classic Commodore systems, and moving projects onto less common machines helps keep knowledge of their programming models alive. Modern flash storage and emulation also make obscure hardware easier to develop for and test without limiting the audience solely to people who own a perfectly preserved original computer. At the same time, the resulting software can still run on real machines, preserving the essential distinction between authentic homebrew and retro-styled contemporary games. The Plus/4 may have failed Commodore commercially in the 1980s, but in 2026 that failure has become part of its charm. There are fewer expectations, fewer exhausted genres and considerably more unexplored territory.
