About Opcode Games
What We Do
ColecoVision Development
Opcode Games develops all ColecoVision titles internally under the direction of Ed Mello.
This includes:
Arcade conversions
Original titles
Super Game Module-enhanced releases
Super Game Club exclusives
Special editions and remasters
Every project is designed to push the platform as far as it can go.
Standard Publishing
For developers who don’t enter the long-term partnership/premium publishing program, Opcode Games offers a standard publishing path:
Professional cartridge manufacturing
Deluxe packaging and manuals
Production through Opcode Electronics
Distribution through the Opcode Store
Marketing support across our channels
This option is ideal for developers who want high-quality physical releases without needing to align with a multi-year premium partnership.
Powered by Opcode Electronics
All Opcode Games releases benefit from the full production and hardware pipeline of Opcode Electronics:
Custom-molded cartridges
High-end printing and packaging
Magazine promotion
Club integration (Elite Challenge, cards)
Logistics and fulfillment
Hardware engineering and PCB design
This is what allows Opcode Games to deliver collector-grade editions consistently.
