Welcome to the Great Sega SC-3000 Survivors Multicart / MEGACART Project

SC-3000 Survivors MEGACART (2018)

Order Now!

Update: 3 Mar 2024 : Hi All. I'm just trying to catch up on the people who contacted me over the past few months. I'll prioritize them then probably take another break until around May. I'm sorry if you haven't received a reply yet. That's just how I make this hobby work around work / family life - I make a few, then I ignore my emails for a few months until I get another block of time.

The Megacart is super cool though :) It even supports some converted Coleco and MSX titles now like Gyruss, Time Pilot, and Tutankham as well as the SC-3000 tape software etc.

So check out the buy page to register your interest for the next batch and I will (eventually) contact you when I have more available. Your best bet to eventually get one is to let me know you're interested, then send me a polite follow up if you haven't heard anything for a few weeks. This is a hobby, not a job :)

In the meantime you can enjoy this timelapse video showing what it takes to assemble a Megacart.

Update: 30 May 2019 :Try out the SC-3000 / SG-1000 Megacart yourself in the MAME emulator. We are still building a few of these for genuine enthusiasts but it may take a while. And if you just want to play in the emulator, that's cool too.

Xevious on the Sega SC-3000... 14 Dec 2011

SMSPower released a dump of Xevious for the Korean Gamboy / Master System clone. But since this runs in legacy mode I wanted to try it on the Sega SC-3000. The original ROM has a couple of errors that stop it working properly with the TMS9929A VDP, but I fixed those. Enjoy!

These pages are dedicated to designing and building home brew Multicarts for the Sega SC-3000. We have instructions on how to build your own 32-n-1 Multicart and we will periodically update with new ideas we are working on. This site is a work in progress, so let us know what you think.

Why? Three reasons:

Let me just get the disclaimer out of the way right at the start:


We take no responsibility for any damage caused to you, your property, your favourite cat, dog, pet bird, Uncle Bob, or Aunt May by the use or misuse of the information contained in the SC-3000 Survivors Multicart Project. We've done our best to come up with a project that is relatively safe and simple, but everything you do is at your own risk.

Nuff said.
