New 8-Bit Programming Game • Steam Playtest

ChipWits Worlds

ChipWits Worlds is a cycle-accurate 8-bit programming game and 3D robotics engineering sandbox powered by genuine 65C02 emulated CPUs.

Write real 65C02 assembly and C code, compile 64 KB boot disks, automate resource harvesting and conveyor logistics, and defend your colony’s power grid from nighttime Electrocrab sieges.

Four Core Engineering Loops in This 8-Bit Programming Game

Every robot in your fleet runs a genuine 8-bit emulated 65C02 processor.

Every instruction takes real clock cycles and real watts.

01 • Real 65C02 Assembly & Colony Logistics

Step-Debug Live Firmware While Your Colony Runs

Open the integrated workstation IDE to write and assemble real 65C02 code like MINE.S. Set breakpoints, single-step through instructions, inspect CPU registers (A, X, Y, SP, PC) and status flags in real time, and watch your robots harvest Silicon and Curium and load them into the Colony Lander.

02 • C64-Era Documentation & Modular OS Disks

Spiral-Bound Reference Guide & 64 KB Boot Disks

Flip through an authentic 1980s-style Programmer’s Reference Guide right at your desk to look up memory-mapped hardware registers, sensor status codes, and interrupt vectors. Flash your compiled programs onto 64 KB floppy boot disks and deploy them across your robot fleet.

Efficiency Race where every instruction costs watts
03 • Hardware Physics & Optimization

Every Instruction Costs Watts

In ChipWits Worlds, code optimization isn’t just for a leaderboard score: it directly governs survival. Busy-waiting in a polling loop drains your battery, while hardware interrupts and tight zero-page routines let your robots run faster, haul more ore per charge, and keep your power grid in the green.

04 • Autonomous Perimeter Defense

Survive the Nighttime Electrocrab Siege

When night falls on Dr. Droog’s world, solar generation drops to zero and swarms of Electrocrabs emerge to short-circuit your infrastructure. Program autonomous sentry robots, coordinate radar and turret networks, and balance your colony’s battery reserves until sunrise.
