Play Wonder Library (Program) Online
You flip through a glitchy digital scrapbook full of Genesis experiments—sketchy music makers, half-baked demos, and a calculator that looks like it was drawn in MS Paint.

Wonder Library was a Sega Genesis release, though it never saw a formal commercial launch. It feels like a collection of tech demos and small experiments, a digital archive of what developers were tinkering with on the hardware. You don't play a game so much as browse a strange, unfinished museum of 16-bit concepts.
You navigate a menu of small programs, from a simple music sequencer to a basic drawing tool. There is no overarching goal, just exploration. You might test a rudimentary platformer stage, fiddle with a sound generator, or poke at a calculator with blocky graphics. The pacing is entirely self-directed, and the difficulty lies more in deciphering the purpose of each tool than in overcoming challenges. It feels like rummaging through a forgotten box of prototype software, each item a brief glimpse into a process rather than a polished product.
