Sorry I haven't been around for a while. I'll update the first post with the plugin on the front page now.

Well...I have tried to find JP to US SMS converter but I can't find any merchandise.
So,I can make that by comparing JP and US SMS pinouts.
But maybe that's not the point.

You should indeed be able to build an adapter with a suitable cartridge socket. As you say, the pins are in a different order, but route them through to the correct pins on a megadrive edge connector (no point making a JAP > US/PAL master system adapter, it would probably be a bit unstable), and the retrode should be able to read it.

Some useful links:
Various Sega pinouts
where to connect the signals to on the megadrive cart

If you build one, let us know :)

Thank you very much for showing some useful informations! :)

I made this table via above links.Is it correct?

I would get a Retrode if it will work for me thanks for any advice.

You are right, wont work.
I done some more research on that adapter and it only emulates the Snes controllers
and has av jack on the side of the adapter.

Something I wouldn't mind knowing. Since Stone Age Gamer is sold out of the Master System adapter, I'm wondering if this might be an acceptable alternative: http://www.stoneagegamer.com/powerbase-mini.html
Some times modern video game characters chase older ones. Some times older video game characters just say the wrong thing.

No. Won't work.

I no longer sell the Retrode. For sales inquiries, please contact our friends at DragonBox.

Well it seems that I've missed the boat on all the expanded feature goodness. I purchased a unit around this time last year, now its a year later, I've had virtually no time to explore the retrode any further. At the time I was simply content to get Donkey Kong Country up and running again after they had been mysteriously pulled from Nintendo's virtual console. Now that I've played that game forwards and backwards, I wanted to see about exploring more of the obscure titles that you can't find from an official retailer.

http://static.giantbomb.com/uploads/original/0/1073/1399077-1b.jpg

N64 and Gameboy functionality was a feature that greatly attracted me to this product, but as far as the website's status at the time, I found myself a little confused about what I would be buying to accomplish those capabilities. Suffice to say that something that can perform as combined solution "GBx/N64" seemed like a dream come true, however the unfortunate truth is that I'm really a novice to DIY schematics projects, especially those that merge different (complex) systems together.

I'm aware that these plugin adapters have been developed as standalone units,
(https://www.retrode.com/plug-in-adapters/)
 the idea is solid, utilize the SMS port due to the similarities between the cartridge and the N64, Gameboy, (and even Virtual Boy) carts. You fine fellows over at retrode HQ made it work, I won't question the logic. My only thing  concern is, if I had to do it all myself, where would I start?

I've got an old Gameboy advance that I no longer use and even some of those Transfer Paks designed for Pokemon and Perfect Dark.  I can always purchase some units As Is online so performing some experimental reverse engineering wouldn't be a problem. Essentially,  I guess what I'm asking is how I would go about deciphering the logic behind the concept of a plug in adapter.

I'm not even sure how to even search for a topic like this, so I understand if I'm off base by making a post here. I  appreciate any redirection so I can get to studying the matter.

I have the same question. I have also been unable to find retrode N64 or gbx plugins to purchase... I love a challenge and generally tend to believe I can do anything (with wildly varying results) but don't have much experience with electronics past resoldering broken/loose connections. Like Cosmos I have parts of old consoles I thankfully never got rid of (someday I was going to fix them...).
I see the n64/gbx combo information on the community plug-ins page (http://www.retrode.org/plug-in-adapters/) but then there's a warning about needing a voltage converter... aside from a sports game I don't have any n64 games I want to fry  :o
Obviously the official plug-in didn't have that problem, did it? Are the schematics for those official plug-ins available as well?
Is there a source for these pcbs somewhere that I can add components to?

Thanks for any advice or information you could provide!

Voltage selection/converter [Re: Adaptors]
« Reply #159 on: 07/Sep/2014 03:13:35 PM »
I see the n64/gbx combo information on the community plug-ins page (http://www.retrode.org/plug-in-adapters/) but then there's a warning about needing a voltage converter...

For 3.3V operation, the Retrode 1 needed an external voltage converter, which was plugged onto the USB cable.

The Retrode 2 has the voltage converter built in. The voltage selection switch is reachable through the SNES slot.


Obviously the official plug-in didn't have that problem, did it?

Both the initial N64/GBx combo plugin as well as the newer, separate N64 and GBx plugins have that problem - or more precisely: The N64 and GB Advance cartridges have that problem that they need 3.3V, and the plugins themselves do nothing about it. :) See above.

The external voltage converter was sold along with the initial N64/GBx plugin. The newer plugins came without it (at least mine did), because at that time, the Retrode 2 was already available.

Awesome, thanks Wannado!
Does the voltage switch change the voltage for both slots or just the genesis slot?
Why did they separate the gbx/n64 adapter later? To add the controller ports?
Maybe I should wait to ask more questions until I receive my Retrode from Dragonbox...  ;)
Sigh... still looking for that gbx adapter meanwhile!

Thanks!
Dan.

AFAIK, the voltage converter works directly on the USB power supply lines, so the switch selects the voltage for the whole Retrode - the processor, both slots, all controller ports. (Otherwise you'd have to run some 40 signal lines through the converter individually...)

Why did they separate the gbx/n64 adapter later? To add the controller ports?

I can only guess, but the combo plugin had the N64 slot on its front face, while the new plugin has the slot on the top edge, which not only makes room for the controller ports, but also enables the Retrode to keep its balance while one of those heavy N64 cartridges is inserted. Also, the new plugins have shells. More slots mean more cut-outs, more difficult assembly, more defective units, increased cost.

I sure am.

Has anything been made available regarding trying to build a gbx adapter on your own?  I understand if they're sold out and you're not making more, but if I can just get the full board diagram and such for it I will do whatever it takes to build my own.  I HAVE the parts I'd need...
