MyCard and Game Gear slot alternatives
Post Posted: Mon Jul 08, 2019 7:06 pm
Are there any known alternatives for the MyCard and/or Game Gear physical cart slots? I know most of the vertical cart slots for consoles are easy to find/make from things like standard edge connectors but these are anything but standard.

You can get sockets for those from a card catcher or a game genie.. but thats still destroying things to get them.

Nothing off the shelf is a straight fit as far as im aware. You could probably make something using a small circuit board and some pogo pins. I was going to do that for a mycard but decided to break open a card catcher instead.

Thanks, Its a thought... Game Genie or Card Catcher sourcing might be my best bet. The main reason i need these is because I'm building a Sega EEPROM burner and general cart reader that'll work with all Sega 8 and 16 bit carts (i currently have full support for home console cartridges but not GG carts or MyCards). I'm also trying to make a slim adapter for the MegaDrive/Genesis that will have both the SMS slot and MyCard slot but sourcing the MyCard slot for a decent price and a less destructive nature has not been possible for me at the moment.

There is a retron 5 adapter that has master system, my card and game gear on it.. possibly that could be helpful? Its still an expensive way to do it though.

I wonder if they are making their own connectors or found a source of nos connectors?

I can look into it, one of their company reps follows me on Instagram so maybe they might know. I wouldn't doubt it if they made their own but with that cheap plastic they use for the system and like aluminum pins or something for the conductors.

You could also try to contact the people at Analogue. They have an adaptor for Game Gear carts for their Mega SG in the works, and that one will most certainly be made of quality materials.

Also a good idea!

Looks like they have a mycard one too.

Time for me to find my sole card and start to measure it to see if I can make a 3D-printable card reader.
I made a adapter for GameCube memory cards so it should work.

If you need any hi res photos and caliper measurements for the Sega card and GG ports on my retron5 adapter, let me know. Luckily the game gear slot is exactly the same just lengthened for the extra pins.

@Enforcer and @MrSVCD
I have a removed GG slot that I can also get caliper measurements on for you as well but not MyCard.

What about the connector used on for old agp bus hraphics cardd on the pc? Those had two rows of offset contacts.. not sure what the spacing was though, plus itd need modifying some what.

I thought of that as well but when i looked at the spacing when comparing it to one of my old cards, the AGP slots pitch is super fine compared to the GG and MyCard. I thought about maybe removing pins but the pitch still causes it not to line up well. I even looked at the pitch of an old slotted CPU and its just as fine as AGP. I cant think of any other slot that used that dual row setup.

Ive just brought a bunch of these to have a look at.. they are 2mm wide at the flange, which is perfect as its a 2.54mm pitch on the games. They are short enough to fit within a game gear cart too.. so could be a winner. The 2mm length ones should go perfectly through 1.6mm circuit board and still have enough spring in it, making it rather easy to build.

I found this

http://www.tototek.com/store/index.php?main_page=product_info&cPath=22&products_id=217&zenid=9uoqc3lv26qa2idmjt430sgmc5

Its currently sold out but one of my friends managed to order a few before hand. They unfortunately did not have the MyCard slot, but maybe you could mod one of these to take them? either way it seems like it a pretty fair price for a custom slot.
