    Beware: Neo Geo Extender Cables!

    Wasn't sure whether to post it here or under tech support but I wanted to make you all aware of dodgy extenstion cables for your neo geo controller. I bought these of ebay.

    https://www.ebay.co.uk/itm/2-x-Exten...53.m2749.l2649

    In short they caused some form of short on the console when pressing up on the joystick making the AES reset itself. I have a video of this which can be seen here.

    Extension cables were tested on 2 AES consoles and 2 joysticks all with the same result. Unfortunately the up fuction on the joystick in the video no longer works

    Sounds like a feature to me. But in all seriousness, I hope it hadn't fried anything.

    Sounds like you had a bad cable.

    I have brought the same cables before and had no issues.

    You should contact the seller though.

    I have gone through hundreds of these cables hacking the Neo Mini pads and making a few joysticks for myself and friends. They come in bags of fifty, at about a rate of three or so per bag being faulty in some way by my personal experience. Most of the time you just need to pop open the hard plastic end pieces with a razor blade and undo a short where two wires overlap one another before they go into the pin headers. Chinese quality control.

    In my opinion the big reason to avoid using these (as an extension cable) is the socket end is pure crap. Just straight metal rods with no beveling to the pins. They're fine if you're just plugging another Chinese cable into them, but are hard on original SNK plugs, potentially damaging them.

    Iíve noticed that from pictures. I opted to pick up a DB15 cable from monoprice rather than one of these extension cables. While it doesnít match the factory cable of the AES joy sticks, I feel much more comfortable hooking everything up.

    I have 4 of these. One problem is the death grip on the console side. Worried I'm going to rip my controller sockets loose.

    Maybe I should stick with the old hacked up DB15 PC extensions I used before.

    Both cables were the same. I’ll have to open them up as advised and see if there are any crossed wires. To be honest though I’m a bit wary of even testing them again as I am worried they may cause more damage.

    Anybody have any clues how to potentially repair the joystick?

    I grabbed a couple extenders from castlemania games last year - these work great. I think they were mfd by RetroBit.

    The ones with those big connectors are garbage. The male end definitely has the potential to damage whatever you plug into it because the pins are over-sized and not chamfered. You can potentially push the female pins back into the controller plug and ruin the connector with them.

    These are the ones I use for all of my arcade stick builds: https://console5.com/store/neo-geo-a...es-6-1-8m.html

    They're much better and the pins have at least some bevel to them to give you a fighting chance. The fit is still slightly tight but not worryingly so like the ones with the large connectors.

    Iíd start with replacing the micro switch. I canít think of any other point of failure. Check the pins of the controllerís plug too, in case they were damaged by the extension cable.

    More likely the plug to of got damaged if anything, You would have to seriously go some to fuck up a micro switch.

    Easy to check with a multimeter though.

    Even though I have used several of these cables I have always ended up chopping off the socket end. I have only ever needed the plug end to make joysticks up and I used one for a Famicom controller adapter so never noticed the quality of the pins.

    Yeah, I have a couple I bought from someone on here and after filing down the connector to the AES they work fine and I can use my Hori and MAS sticks with it and have no problems. I've since bought a few of the same cables you linked to via console 5 for my Neo CD and consolized MVS.

    You're right, they're junk. I edited my previous post.

    Guys thanks for the posts. Opened up the DB15 plug to find the oversized male pins on the extender had pushed 2 of the female pins back.

    Wouldnít of thought to have checked without the posts.

    Yes. I forgot to say I pushed them back in and the controller works again

    Yeah mine ended up destroying my snk cable, so I had to buy another extension cable and solder it to the joystick, and had to throw out the original cable.
    Alright, back again with THE IMMORTAL JOHN HANCOCK
