Another noob question, will Mark III carts only work on a Mark III ?

Will Mark III carts only work on a Mark III ? I know they physically fit the SG-1000 and SC-3000 (but don't work), and they are a different size to the SMS carts.
I have a SMS, but it's stored away somewhere, I need to find it :) |

Japanese Sega Mark III cartridges work only on Japanese Sega Mark IIIs, Japanese Master Systems and Korean Gam*Boy systems. At least one game (Hang On) has code to detect an SG-1000 and plays a special tune, but I’m not aware of any other examples of doing anything when plugged into the older systems. | |

Thanks, I just wanted to check because I have Afterburner for the Mark III.
Maybe I could burn a SG-1000 game ROM and put it in that cartridge's case? |

I've seen a number of US to Japanese adapters, but is there a good quality Japan to US cart adapter, or is it better to find a Japanese Master System? For my purposes I'm ignoring the FM audio differences as I've already got an FM board mod installed in my US system. | |

You would also need a BIOS mod because the Japanese carts will be rejected. | |

I was thinking it would just be the code in the ROM that isn't compatible, is there a region chip in these cartridges? |

no chip, but the European and American SMS BIOSes check for a specific signature (and checksum) in the ROM data.
Japanese games don't have that in their ROMs. |

But wouldn't that mean if I fit a new ROM it would work? |

They're discussing using Japanese SMS games on a Western SMS, the bios can be an issue for some games with regards to that. What I presume that you're proposing (using Mark III Afterburner as a donor cart for an SG-1000 rom to play on an SC-3000) won't have that issue (SC-3000 doesn't have a bios for one reason). So software-wise that will be fine. Afterburner is a big game though, so has a mapper (I think only Sherlock Holmes requires one on SG-1000), so I'm not sure if that needs to be taken into account on the hardware side. |

You can buy an adapter that is compliant with the BIOS checks from there: https://www.arcade-projects.com/threads/announcement-coming-soon-apocalypses-fir... |

Jumping into the conversation, is it available? You shared with me the link and I "thought" it was an announcement, as there's no contact no link to buy it | |

If you don't need/want a shell it is available yes.
It does fit in an OG shell if you cut a slot at the top. High quality PCBs (hard gold and bevelled edge). |

Yes you can, there's contact information in the thread there if you don't want to register. | |

great thanks! | |

Is there an estimation on when would the adapter with a shell (and collectors edition) be available?
Not in a hurry so I can totally wait. But maybe getting shells done involves a lot of work and will take a long time, so in that case maybe better to pick one now. PS: it's great to be able to order by e-mail without needing to register. |

Hi Jair,
Our best option for the shells right now is to order repros and have them CNCed to create an opening at the top. This is not a small investment compared to the very few number of units we plan to sell. |

Thank you Apocalypse.
Then I’ll just go ahead and order. It’s great this product even exists, I don’t want to give you extra work. |
