JT Studios is now selling the same excellent $25 SMS to MK-2000 cartridge adapter from Retro Game Restore that I demo’d a few months ago, however they’re also offering a 3D printed case for an extra $15. This allows you to use Sega Master System game cartridges – As well as ROM carts like the Master Everdrive x7 – In Japanese SMS consoles, like the MK-2000 pictured above. If you already have a 3D printer, the file is still available to print your own and you can just order the PCB. More info after the links:

Personally, I think this is the perfect choice for people who own the Japanese SMS, model MK-2000 with the built-in 3D Glasses adapter, FM Sound chip and Rapid Fire Module. While sure, you can just get a cartridge adapter and stack the Everdrive (or any other SMS game) on top of it, that results in a tall, kinda unstable look. And of course, you can just get the rear adapter, but that requires you to cut some case plastic and could potentially have some compatibility issues.
This combination of PCB and 3D printed case provides the look of a standard MK-2000 game, with the same compatibility as just using an Everdrive; Some games will always have PAL/NTSC issues and others will always run with Japanese text when used with a JP BIOS, but this cartridge adapter doesn’t affect that in any way. Previously, some adapters had issues with certain games and this doesn’t seem to have those – At least with the games I tried.
I’m still waiting for someone to make an authentic label for it though ;p And of course, an injection-molded version would always look better, however at the quantities these will be sold, it would probably be too expensive to justify the cost. Oh well, I can always hope…
