ColecoVision Super Game Module

This cartridge device is designed to be plugged into the main expansion port, located on the front side of your ColecoVision console. It upgrades your ColecoVision with 24 kilobytes of extra RAM, adds a new sound chip and a parallel port for future peripheral connection.

Most of Opcode Games' future ColecoVision releases will require more than the console's single kilobyte of onboard RAM, so using the ColecoVision Super Game Module for those games will be mandatory.

MegaCart

Regular ColecoVision cartridges are limited to 32 kilobytes of ROM data. This, along with the ColecoVision's single kilobyte of RAM, severely limits the kinds of games that can be coded for the console. Titles like Gateway to Apshai are probably the most elaborate games you're going to see within these harsh hardware limits.

20+ years after the commercial death of the ColecoVision, Opcode Games is proud to introduce a solution to the ColecoVision's 32-kilobyte ROM limit: The MegaCart! This piece of hardware designed by Bryan Edewaard, which fits into a regular ColecoVision cartridge shell, implements bankswitching schemes that go far beyond 32K. There are several variations of the MegaCart: 128K, 256K, 512K and 1024K.
