It looks like this guy may have sold some connectors to db electronics. You might be able to check if he still has any available.

Edit: It looks like they're sold on Amazon Japan too.

i made this awhile back, it allows me to play sega cards on the master system model 2, play sega cards on the game gear with a master gear converter as well as dump sega cards on my retrode using a master system plugin.






although ive never tried im guessing it will also do SG-1000 cards too.

@hadess whats wrong with just using that markiii to megadrive converter with the retrode? The schematic looks pretty straight forward so it should work.

I'm still hoping for a solution to this problem, too. My Japanese Phantasy Star cart sits alone, waiting to be dumped. Gotta have that superior Mark III music! 8)

General Discussion / Need a bit of help making a Mark III adapter

Hey!

I have a fully loaded Retrode 2, including the Master System adapter, but I've been buying a few Japanese Mark III/Master System games which I wanted to be able to dump.

There's a couple of threads already about various third-party adapters being tested, none working from what I can tell. So I thought I'd "make" my own. Here's my thinking, and do stop me if any of this sounds wrong.

1. Find the physical bits needed to connect everything. That was relatively easy. After spending a couple of hours (!) on electronics supply sites, the cheapest way to get a MegaDrive connector on one end, with a Mark III connector on the other is Raphnet's Mark III for Megadrive adapter:
http://www.raphnet-tech.com/products/brd_markIII_to_smd/index.php
and here are the schematics for it:
http://www.raphnet-tech.com/downloads/markIII_to_smd_schematic.png

2. Let's forget the above for a moment, and find out how the SMS adapter is pinned out. I found this:
http://consolingmyself.co.uk/post/18692678762/retrode-sms-gg-plug-in-adapter-pin-out
Is this still accurate? Let's assume it is and move on.

3. We need to find out what the differences are between the SMS and the Mark III pinouts. I found this on SMS Power:
http://www.smspower.org/Development/JapaneseSMSCartridge

And at this point I'm kind of stumped as to how to use all this information. I think I'm missing an "export SMS to Mark III diagram" somewhere. Ideally, it'd support Mark III and Japanese SMS games[1], but I already see some difference in wiring for some lines that the Retrode uses (though I could have had my numbers crossed).

Any ideas? Cheers

[1]: Bonus point if I can dump those 2 SG-1000 cartridges I have ;)

The other way to do it is to overdump and then use a site like Dat-o-Matic to get the correct ROM size and trim the end of your ROM to the correct length. If the checksum matches afterwards, you got a good dump.

1) Clean the game contacts, sometimes a 0 kb message just means it can't read the game.
2) Try using the "Force" config options to force the size to the correct size.

The contacts were already cleaned, but the suggestion with the configuration was the solution. With forceSystem gba (probably not necessary) and forceSize 32 I was able to dump the ROM. Thank you very much. :D
I had to force the file size to get a good dump on Paper Mario, from what I understand GBA and N64 games do not have any information in the ROM that the Retrode can read to determine the correct ROM size.

Today I tried to dump Mother 3 but it didn't work. Although a file named Mother3.A3UJ.gba is displayed, but it's 0 kb in size. I've tried it several times, but it doesn't work. :(

Is there a known issue with Mother 3? I use a Retrode 2 (from dragonbox) with the firmware v0.22.

Two things to try:

1) Clean the game contacts, sometimes a 0 kb message just means it can't read the game.
2) Try using the "Force" config options to force the size to the correct size.

Tales of Phantasia works on the new firmware .22 from Skaman.  The other 2 should be fine as they are standard games
