A hand-assembled Atari 2600 cartridge inspired by Pennsylvania’s most unpredictable highway. Dodge traffic, potholes, and parked cars, and set the fastest time.
Watch out — this isn’t a joy ride, it’s Route 22. Race past Tower 22 five times and set the fastest time. Survive traffic, dodge hazards, and prove you’ve got what it takes to handle the Valley’s roughest ride. On the title screen, move the joystick to toggle hazards: Down for Pothole Mode, Up for Damage On/Off, Right to remove parked cars, and Fire to honk (maybe they’ll move… maybe).
Behind the Work
Process notes
Development notes
Developed using a mix of 6502 assembly and Batari Basic, Route 22 Rampage pushes the Atari 2600 to new limits. What started as an experiment in low-level programming grew into a full game inspired by Pennsylvania’s most unpredictable highway. Each 16 KB cartridge is built, tested, and assembled by hand in the Lehigh Valley. The limited physical run of 42 cartridges has sold out; the digital ROM lives on.
